A non‐targeted, ultra‐high‐resolution mass spectrometric, direct analysis of oak‐wood extracts from two species (Quercus robur L. and Quercus petraea Liebl.) from three French forests, and of a wine aged in barrels derived therefrom has been performed to identify families of metabolites that could discriminate both the species and the geographical origin of woods. From 12 T ultra‐high‐resolution Fourier transform ion cyclotron resonance mass spectra of wood extracts, hundreds of mass signals were identified as possible significant biomarkers of the two species, with phenolic and carbohydrate moieties leading the differentiation between Q. robur and Q. petraea, respectively, as corroborated by both FTMS and NMR data. For the first time, it is shown that oak woods can also be discriminated on the basis of hundreds of forest‐related compounds, and particular emphasis is put on sessile oaks from the Tronçais forest, for which sugars are significantly discriminant. Despite the higher complexity and diversity of wine metabolites, forest‐related compounds can also be detected in wines aged in related barrels. It is only by using these non‐targeted analyses that such innovative results, which reveal specific chemodiversities of natural materials, can be obtained.
Molecular Self‐Recognition: Rotational Spectra of the Dimeric 2‐Fluoroethanol Conformers
Authors: Liu Xunchen , Borho Nicole , Xu Yunjie
Published: November 2008

Fluoroalcohols show competitive formation of intra‐ and intermolecular hydrogen bonds, a property that may be crucial for the protein‐altering process in a fluoroalcohol/water solution. In this study, we examine the intra‐ and intermolecular interactions of 2‐fluoroethanol (FE) in its dimeric conformers by using rotational spectroscopy and ab initio calculations. Three pairs of homo‐ and heterochiral dimeric FE conformers are predicted to be local minima at the MP2/6‐311++G(d,p) level of theory. They are solely made of the slightly distorted most stable G+g−/G−g+ FE monomer units. Jet‐cooled rotational spectra of four out of the six predicted dimeric conformers were observed and unambiguously assigned for the first time. All four observed dimeric conformers have compact geometries in which the fluoromethyl group of the acceptor tilts towards the donor and ensures a large contact area. Experimentally, the insertion of the OH group of one FE subunit into the intramolecular OH⋅⋅⋅F bond of the other was found to lead to a higher stabilisation than the pure association through an intermolecular OH⋅⋅⋅OH link. The hetero‐ and homochiral combinations were observed to be preferred in the inserted and the associated dimeric conformers, respectively. The experimental rotational constants and the stability ordering are compared with the ab initio calculations at the MP2 level with the 6‐311++G(d,p) and aug‐cc‐pVTZ basis sets. The effects of fluorination and the competing inter‐ and intramolecular hydrogen bonds on the stability of the dimeric FE conformers are discussed.

Perspektiven der Biothermodynamik III. Thermische Stabilität von Proteinen
Authors: Keller J. U.
Published: November 2008

Die Anwendung von Begriffen und Methoden der Thermodynamik der Gleichgewichte und der Vorgänge auf Systeme und Prozesse der Biotechnologie hat zur Bildung eines neuen Fachgebietes geführt, der technischen Biothermodynamik. Der vorliegende Artikel ist der dritte einer Reihe, in der versucht wird, einen Überblick über die Grundlagen und Möglichkeiten, die dieses Gebiet dem Verfahrensingenieur eröffnen, zu geben und dies auch an einzelnen Beispielen zu demonstrieren. In diesem Artikel wird das Problem der thermischen Stabilität von Proteinen in Lösungen thermodynamisch analysiert. Dabei wird der Übergang eines Proteins aus seinem natürlichen Zustand in einen (beliebigen) denaturierten Zustand als quasichemische Reaktion modelliert. Als Beispiel wird die thermische Stabilität von Myoglobin in wässriger Lösung mit Hilfe kalorischer Messdaten analysiert. Dabei zeigt sich, dass dieses Protein sowohl bei zu hohen als auch zu niedrigen Temperaturen denaturiert.
A Comparative Study of the Use of Organoclay‐Based Formulations and Organic Amendment to Reduce the Leaching of the Herbicide MCPA in Soil
Authors: Cabrera Alegría , Trigo Carmen , Cox Lucía , Celis Rafael , Cornejo Juan
Published: November 2008

MCPA (4‐chloro‐2‐methylphenoxyacetic acid) is an acidic herbicide widely used on olive crops in Spain. Due to its anionic form at natural soil pH, there is high risk of leaching and groundwater contamination by the use of this herbicide. The aim of this work was to study the effects of organoclay‐based formulations of MCPA and olive oil waste amendment on MCPA leaching in a sandy loam soil. For this purpose, batch adsorption and column leaching studies were performed. The organoclays used to prepare the clay‐based formulations of MCPA were obtained by treating Wyoming montmorillonite (SWy‐2) and Arizona montmorillonite (SAz‐1) with an amount of hexadecyltrimethylammonium (HDTMA) cation equal to 100% of the CEC of the montmorillonites. The organic residue used in this study was a solid waste from olive oil production (olive oil waste, OOW). The soil was amended with the organic residue at the rate of 10% (w/w). Batch release and column leaching studies indicated that organoclay‐based formulations of MCPA reduced the release rate and the leaching of the herbicide as compared to the use of a conventional formulation containing the herbicide in an immediately available form. The increase in soil organic matter of the soil upon amendment with the organic residue also resulted in greater adsorption and reduced leaching of MCPA in the soil. Accordingly, both the use of organoclay‐based formulations and the amendment of soil with OOW are proposed as efficient strategies to reduce extensive leaching losses associated with the application of MCPA in high‐risk scenarios, such as Mediterranean olive groves.
Catalytic Hydrogenolysis of Aromatic Ketones in Mixed Choline–Betainium Ionic Liquids
Authors: Van Doorslaer Charlie , Wahlen Joos , Mertens Pascal G. N. , Thijs Ben , Nockemann Peter , Binnemans Koen , De Vos Dirk E.
Published: November 2008

The palladium‐catalyzed hydrogenolysis of aromatic ketones to alkylbenzenes was studied in mixtures of ionic liquids to explore the promotional effect of these reaction media. Choline‐based ionic liquids displayed complete miscibility with the aromatic ketone substrate at reaction temperature and a clear phase separation of the derived alkylbenzene product at room temperature. Selected ionic liquids were then assessed as reaction media in the hydrogenolysis of aromatic ketones over palladium catalysts. A binary mixture of choline and betainium bis(trifluoromethylsulfonyl)imide ionic liquids resulted in the highest conversion and selectivity values in the hydrogenolysis of acetophenone. At the end of the reaction, the immiscible alkylbenzene separates from the ionic liquid mixture and the pure product phase can be isolated by simple decantation. After optimization of the reaction conditions, high yields (>90 %) of alkylbenzene were obtained in all cases. The catalyst and the ionic liquid could be used at least three times without any loss of activity or selectivity.
Synthesis and Characterization of Novel Biopolyesters from Suberin and Model Comonomers
Authors: Sousa Andreia F. , Gandini Alessandro , Silvestre Armando J. D. , Pascoal Neto Carlos
Published: November 2008

The synthesis of novel polyesters from model long‐chain aliphatic monomers and from suberin reactive aliphatic fragments was conducted using mild polycondensation or polytransesterification conditions. The ensuing polyesters were characterized by means of various techniques. When mixtures of simple suberin‐like monomers were used, the ensuing polyesters had very regular structures, with melting temperatures around 80 °C and glass transitions below room temperature. This first systematic study of the exploitation of suberin as a precursor to novel aliphatic polyesters confirmed the huge potential of using this abundant renewable resource to prepare macromolecular materials for promising applications.
Expectancies related to thinness, dietary restriction, eating, and alcohol consumption in women with bulimia nervosa
Authors: Bruce Kenneth , Mansour Sandra , Steiger Howard
Published: November 2008

Objective:

To investigate behavior‐outcome expectancies relating to thinness, dietary restriction, eating, and alcohol consumption in women with bulimia nervosa (BN).

Method:

Women with BN (N = 29), women with BN and a co‐morbid lifetime alcohol use disorder (AUD; N = 18), and control women (N = 24), completed interviews and questionnaires assessing eating‐ and alcohol‐related symptoms, as well as questionnaires measuring expectancies relating to thinness, dietary restriction, eating, and alcohol consumption.

Results:

Compared with the control group, both bulimic groups reported greater positive expectancies relating to thinness, dietary restriction and eating; expectancy endorsements were also predictive of the severity of eating‐related symptoms. Compared with the other groups, the bulimic group with comorbid lifetime AUD had elevated positive alcohol‐related expectancies, and alcohol expectancy endorsements predicted severity of alcohol‐related symptoms.

Discussion:

Women with BN endorsed more positive expectancies relating to thinness, dietary restriction, and eating, whereas women with BN and a lifetime comorbid AUD endorsed more positive alcohol expectancies. The results are consistent with expectancy theory in that positive expectancy endorsements were associated with symptom severity in a syndrome‐specific manner.

Regional development, nature production and the techno‐bureaucratic shortcut: the Douro River catchment in Portugal
Authors: Ioris Antonio A. R.
Published: November 2008

The introduction of the Water Framework Directive in Europe represents a unique opportunity to promote more inclusive strategies for the long‐term preservation of (socionatural) water systems. However, the analysis of the Portuguese experience, using the River Douro as a case study, reveals still considerable shortcomings in the assessment of problems and the formulation of solutions. Instead of promoting a meaningful dialogue between social groups and spatial areas, there is a systematic attempt to conform to legal requisites by taking a ‘techno‐bureaucratic’ shortcut that largely reproduces the distortions of previous regulatory approaches. Decisions on water management are part of political disputes about regional development and state reform, such as in relation to the provision of water and electricity by public utilities. Nonetheless, these broader issues have been kept tacitly away from the WFD agenda, which has been concentrated on adjusting established procedures to the (formal) requirements of the new regulation.

The Role of Functionalisation, Asymmetry and Shape of a New Macrocyclic Compartmental Ligand in the Formation of Mononuclear, Homo‐ and Heterodinuclear Lanthanide(III) Complexes
Authors: Tamburini Sergio , Sitran Sergio , Peruzzo Valentina , Vigato Pietro Alessandro
Published: November 2008

The compartmental [1+1] macrocycle H3L, obtained by self‐condensation of the formyl precursor 3,3′‐(3,6‐dioxaoctane‐1,8‐diyldioxy)bis(2‐hydroxybenzaldehyde) with the amine precursor N,N‐bis(2‐aminoethyl)‐2‐hydroxybenzylamine, contains one inner ON3O2 Schiff base and one outer O2O4 crown‐like chamber. According to the experimental conditions it forms, by a template process, the stable mononuclear complexes Ln(H3L)(Cl)2(CH3COO)·nS·mHCl or [Ln(L)]·nS (Ln = La, Lu, Y, Yb, Er, Dy, Tb, Gd, Eu, Ce) with the lanthanide(III) ion encapsulated in the crown‐ether‐like and in the Schiff base site. The mononuclear complexes Ln(H3L)(Cl)2(CH3COO)·nS·mHCl, by further complexation with a different lanthanide(III) ion, give rise to the related heterodinuclear complexes [LnLn′(L)(Cl)2(CH3COO)]·nS while the homodinuclear and the heterodinuclear complexes [Ln2(L)](Cl)3·nH2O and [LnLn′(L)](Cl)3·nS could be prepared by a template reaction using the appropriate molar ratio of reactants. Their properties have been studied by using SEM‐EDS microscopy, IR and NMR spectroscopy and their compositions confirmed by thermal and ESI‐Mass spectrometric analyses. In the heterodinuclear complexes, the site occupancy of the different lanthanide(III) ions was determined by 1H and 13C NMR spectroscopy in CD3OD or (CD3)2SO – it was found that heterodinuclear complexation occurs in methanol with the smaller lanthanide(III) ion mainly coordinating to the Schiff base site and the larger lanthanide(III) ion to the crown site whereas, in dimethyl sulfoxide, demetalation of the weaker coordinated lanthanide(III) ion into the crown ether chamber occurs with the subsequent formation of mononuclear species in solution. The thermal decomposition of the heterodinuclear complexes forms the related mixed oxides, the stoichiometries and properties of which were determined by SEM‐EDS microscopy and X‐ray powder diffraction studies (XRD).

Published: November 2008

Two (polypyridyl)ruthenium(II) complexes, [(tpy)RuII(L)](PF6)2 (1) and [(tpy)RuII(L)RuII(tpy)](PF6)4 (2) {tpy is 2,2′:6′,2″‐terpyridine and L is 1,4‐bis[(2,6‐dipyrazol‐1‐yl)pyrid‐4‐yl]benzene}, were synthesised and studied in view of their electrochemical and photophysical properties. The structural characterisation of 1 and 2 was carried out by 1H and 13C NMR spectroscopy, MALDI‐TOF/ESI mass spectrometry and single‐crystal X‐ray analysis. The spectro‐ and electrochemical consequences of the introduction of 2,6‐dipyrazol‐1‐ylpyridine coordinating units into RuII polypyridyl complexes were investigated by UV/Vis, low‐temperature emission spectroscopy and square‐wave voltammetry. It was shown that ligand L can be used as a back‐to‐back bridging ligand in the construction of multinuclear ruthenium(II) ion arrays. In comparison to the widely used 2,2′:6′,2″‐terpyridyl system, the 2,6‐dipyrazol‐1‐ylpyrid‐4‐yl unit was found to act as a relatively strong σ‐donor and weak π‐acceptor ligand which allows its use as a structural and electronic alternative in multinuclear architectures.(© Wiley‐VCH Verlag GmbH & Co.

Total Synthesis of Candicanoside A, a Rearranged Cholestane Disaccharide, and Its 4″‐O‐(p‐Methoxybenzoate) Congener
Authors: Tang Pingping , Yu Biao
Published: November 2008

Candicanoside A (1) and its 4″‐O‐(p‐methoxybenzoate) derivative 2 are congeners of the novel 24(23→22)abeo‐cholestane glycosides that occur in the genus Ornithogalum indigenous to Southern Africa and have remarkable cytostatic activities. These two saponins have been synthesized starting from dehydroisoandrosterone, D‐glucose, and L‐rhamnose in 37 and 44 steps, respectively. The reaction protocols feature a stereocontrolled stepwise glycosylation with glycosyl imidates as the donors. The synthesis of the rearranged steroid aglycon employs a 20‐alkoxy radical‐mediated functionalization of the angular 18‐methyl group, a Johnson–Claisen rearrangement for the alkylation at C‐20, an aldol condensation at C‐22, and a photodeconjugation of an α,β‐unsaturated lactone as the key steps.

New Route to the Synthesis of the Isocryptolepine Alkaloid and Its Related Skeletons Using a Modified Pictet–Spengler Reaction
Authors: Agarwal Piyush K. , Sawant Devesh , Sharma Sunil , Kundu Bijoy
Published: November 2008

A new route to the synthesis of the isocryptolepine alkaloid with antimalarial activity using a modified Pictet–Spengler reaction has been devised. The strategy was then used to generate libraries based on three structural variants of the alkaloid. Compounds based on these three variants in general were accessed in three steps through a modified Pictet–Spengler cyclization reaction as the key step. The C‐2‐, C‐3‐, or N‐1‐linked (aminoaryl)indoles (8, 12, 13) required for cyclization were obtained by treating the corresponding indoles with o‐halonitrobenzene using either nucleophilic replacement or Pd‐based chemistry (Heck/Suzuki reaction) followed by reduction of the nitroaryl functionality. The substrates 8, 12, and 13 were then subjected to the Pictet–Spengler reaction to furnish polycyclic structures, indolo‐quinolines 4 and 19 and indolo‐quinoxalines 20 with three‐point diversity in high yields and purities. One of the indolo‐quinolines 4a after treatment with CH3I furnished the isocryptolepine alkaloid in excellent yield. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
Change processes for attractive work in small manufacturing companies
Authors: Åteg Mattias , Andersson Ing‐Marie , Rosén Gunnar
Published: November 2008

The article originates from research in interaction between researchers and companies in a network, which has led to an increasing awareness among managers on issues such as reasons behind difficulties in attracting competent labor. Particularly, attention has been directed toward the importance of work environment improvements that increase the attractivity of industrial work. To deal with such challenges, for more than 5 years a number of small engineering companies, with research support, have been engaged in change processes based on the concept of attractive work. The purpose of the article is to develop knowledge and understanding for how small engineering companies can create more attractive work. One goal is to make it possible to draw conclusions about the employees' experiences of changes in the attractivity of industrial work. Efforts in this direction have been conducted through work environment assessments (before and after the changes) and through administration of a questionnaire. The results show that it is possible to analyze how employees experience changes in the attractivity of work. This is most interesting from the perspective that the results can be used for assisting further improvements. © 2008 Wiley Periodicals, Inc.
Methods for retrieving hydrologically significant surface parameters from remote sensing: a review for applications to east Asia region
Authors: Matsushita Bunkei , Fukushima Takehiko
Published: November 2008

As human populations and resource use continue to increase, water quality and water resource management will become major problems. With its advantages of large area coverage, high spatial resolution, frequent update and consistent quality, remote sensing has been widely used for hydrological studies and water resources management. This paper focuses on three potential functions of remote sensing for hydrological analysis in east Asia: (1) monitoring water quality in turbid lakes; (2) extracting impervious surface areas (ISAs) from watersheds and (3) estimating evapotranspiration in semi‐arid areas. Reviewing the results of the above three topics, it becomes clear that the ability of the current remote sensing technique is still limited in terms of its use in hydrological simulations. An alternative to improving the sensors is developing effective algorithms to compensate for the limitations of current satellite sensors. Copyright © 2008 John Wiley & Sons, Ltd.
Re Metcalfe: A matter of fraud, fairness, and reasonableness. The restructuring of the third‐party asset‐backed commercial paper market in Canada
Authors: Forte Mario
Published: November 2008

The recent market freeze in third‐party asset‐backed commercial paper in Canada has given rise to a restructuring proceeding of unprecedented size and complexity in Canada. It has led the Courts to refine and perhaps define the interpretative principles underpinning the determination of the scope of under‐inclusive commercial legislation. This paper is a commentary on this unusual proceeding and the judicial analysis employed in the proceeding. Copyright © 2008 John Wiley & Sons, Ltd.
Crop pattern and conjunctive use management: A case study
Authors: Karamouz Mohammad , Zahraie Banafsheh , Kerachian Reza , Eslami Ahmad
Published: November 2008

In this paper, a genetic algorithm model is developed to optimise the crop pattern of irrigation networks, considering water allocation priorities and surface and groundwater availability. The objective function of this model is to maximise the net benefits of agricultural products, considering allowable water table fluctuations, pumping costs, as well as the impacts of water supply deficit on crop production. The model is formulated in such a way that both crop pattern and water allocation from surface or groundwater resources are simultaneously optimized. Due to the large number of decision variables and the non‐linearity of the problem, a genetic algorithm (GA) is used to find the optimal solution. One of the main advantages of the proposed model is consideration of the time series of monthly crop water demand, which allows incorporation of demand uncertainty in the development of optimal operation policies. A production function has also been used to estimate the production rate with respect to the amount of water allocation and water supply deficits. The results of the application of this model to agricultural lands in eight irrigation networks in Tehran province in Iran are also presented in the paper. The results include optimal crop pattern and operating policies for surface and groundwater allocation in a long‐term planning horizon. The results of the model application to Tehran plain have shown a significant change in the area allocated to different crops to provide a higher total benefit.

Published: November 2008

Despite extensive efforts toward elucidation of the molecular pathway controlling cytotrophoblast (CTB) invasion to the uterine decidua, it remains poorly defined. There are striking similarities between tumor cell invasion and cytotrophoblast implantation to the deciduas whereby the role ofProtease Activated Receptors(PARs) andwntsignaling is well recognized. We examine here consequences of modulation of PAR1 and PAR2 expression and function on CTB invasion and β‐catenin stabilization. Toward this end, we utilized a model system of extravillous trophoblast (EVT) organ culture and various placenta cell lines (e.g., JAR and HTR‐8/Svneo). Activation of PAR1 induces EVT invasion whilehPar1‐SiRNA and PAR1 antagonist SCH79797—effectively inhibited it. In parallel, the Wnt inhibitor Dickkopf‐1 (Dkk1) similarly inhibited it. Nuclear localization of β‐catenin is seen only after PAR1 activation, and is markedly reduced following the application ofhPar1‐SiRNA construct and PAR1 antagonist in CTBs. In contrast, PAR2 elicited a low cytoplasmic β‐catenin level as also proliferation and invasion. In the non‐activated CTBs in‐comparison, β‐catenin appeared limited to the membrane pools. Concomitantly, a temporal regulated pattern ofWnt‐4, 5a, 7b, 10a, 10bexpression is seen along PAR1 appearance. Enforced expression ofWntantagonists,Secreted Frizzled Related Proteins;SFRP2 & 5; into HTR‐8/Svneo, resulted with a markedly reduced nuclear β‐catenin levels, similar to the effect obtained byhPar1‐SiRNA treatment. Identification of PAR1 downstream target/s may nonetheless contribute to the formation of a future platform system for eliciting a firm placenta‐uterus interactions and to the definition of late pregnancy outcomes.

Why do some hospital leaders “speak no evil” about their organizations' medical errors?
Authors: Rouse Ruby A. , Kaplan Judith B.
Published: November 2008

Sentinel events, preventable medical errors resulting in serious disability or death, are a significant problem for hospital leaders. Accreditation agencies, such as the Joint Commission, urge hospitals to voluntarily disclose information about medical errors. However, some healthcare leaders “speak no evil” by choosing not to release sentinel‐event data. In an effort to increase the reporting of medical errors, several states passed laws mandating disclosure of sentinel events to the government. The state‐reported medical error rates of Indiana hospitals were compared with their leaders' perceptions of quality of care. Regardless of the number of sentinel events occurring at their hospitals, leaders consistently claimed their organizations provided high‐quality care. Two theories, rationalization and gaming, are presented to explain why leaders do not acknowledge the presence of serious quality‐management problems in their organizations.
Collision‐induced loss of AgH from Ag+ adducts of alkylamines, aminocarboxylic acids and alkyl benzyl ethers leads exclusively to thermodynamically favored product ions
Authors: Schäfer Mathias , Dreiocker Frank , Budzikiewicz Herbert
Published: November 2008

The loss of AgH from [M + Ag]+ precursor ions of tertiary amines, aminocarboxylic acids and aryl alkyl ethers is examined by deuterium labeling combined with collision activation (CA) dissociation experiments. It was possible to demonstrate that the AgH loss process is highly selective toward the hydride abstraction. For tertiary amines and aminocarboxylic acids, hydrogen originates from the α‐methylene group carrying the nitrogen function (formation of an immonium ion). In all cases examined, the most stable, i.e. the thermodynamically favored product ion is formed. In the AgH loss process, a large isotope effect operates discriminating against the loss of D. The [M + Ag]+ ion of benzyl methyl ether loses a hydride ion exclusively from the benzylic methylene group supporting the experimental finding that the AgH loss reaction selectively cleaves the weakest CH bond available.

Analysis of phenolic choline esters from seeds of Arabidopsis thaliana and Brassica napus by capillary liquid chromatography/electrospray‐ tandem mass spectrometry
Authors: Böttcher Christoph , von Roepenack‐Lahaye Edda , Schmidt Jürgen , Clemens Stephan , Scheel Dierk
Published: November 2008

Total phenolic choline ester fractions prepared from seeds of Arabidopsis thaliana and Brassica napus were analyzed by capillary LC/ESI‐QTOF‐MS and direct infusion ESI‐FTICR‐MS. In addition to the dominating sinapoylcholine, 30 phenolic choline esters could be identified based on accurate mass measurements, interpretation of collision‐induced dissociation (CID) mass spectra, and synthesis of selected representatives. The compounds identified so far include substituted hydroxycinnamoyl‐ and hydroxybenzoylcholines, respective monohexosides as well as oxidative coupling products of phenolic choline esters and monolignols. Phenolic choline esters are well separable by reversed‐phase liquid chromatography and sensitively detectable using electrospray ionization mass spectrometry in positive ion mode. CID mass spectra obtained from molecular ions facilitate the characterization of both the type and substitution pattern of such compounds. Therefore, LC/ESI‐MS/MS represents a valuable tool for comprehensive qualitative and quantitative analysis of this compound class. Copyright © 2008 John Wiley & Sons, Ltd.

Published: November 2008

Radiating devices, made up by woodpile electromagnetic bandgap (EBG) material superstrates placed over microstrip patches, are taken in consideration. Much interest is devoted to such antennas because of their enhanced directivity. The radiated far‐field has been calculated using an in‐house finite‐difference time‐domain (FDTD) code. The microstrip position has been changed and the woodpile superstrate has been rotated: the results show interesting properties, useful for the synthesis of such radiating devices.

Synoptically forced hydroclimatology of major Arctic watersheds in general circulation models; Part 1: the Mackenzie River Basin
Authors: Finnis Joel , Cassano John , Holland Marika , Serreze Mark , Uotila Petteri
Published: November 2008

The ability of 14 general circulation models (GCMs) to realistically simulate weather patterns and precipitation regimes affecting the Mackenzie River Basin has been assessed. Applying the method of self‐organizing maps to daily data from the model ensemble and the 40‐year reanalysis project of the ECWMF (ERA‐40), a regional synoptic climatology of sea level pressure was developed and used to analyse the model output. GCM performance, as compared with ERA‐40, varies significantly between models and seasons, but is generally best during the summer and winter. In‐depth examination of a five‐model subset reveals biases in the placement of the Pacific storm track, which may be related to misrepresentations of the Beaufort High. Biases in Mackenzie Basin precipitation are only weakly connected to these circulation errors, and are, instead, primarily the result of inaccurate representations of basin‐scale precipitation regimes. In particular, models allow excessive orographic precipitation along the west coast of North America to intrude into the Mackenzie Basin. These results suggest that projections of the Mackenzie's response to climate change could benefit from climate downscaling studies. Copyright © 2008 Royal Meteorological Society
