Dual-Polarization Radar Rainfall Estimation over Tropical Oceans
Authors: Thompson Elizabeth J. , Rutledge Steven A. , Dolan Brenda , Thurai Merhala , Chandrasekar V. 
Published: December 2017

AbstractDual-polarization radar rainfall estimation relationships have been extensively tested in continental and subtropical coastal rain regimes, with little testing over tropical oceans where the majority of rain on Earth occurs. A 1.5-yr Indo-Pacific warm pool disdrometer dataset was used to quantify the impacts of tropical oceanic drop-size distribution (DSD) variability on dual-polarization radar variables and their resulting utility for rainfall estimation. Variables that were analyzed include differential reflectivity Zdr; specific differential phase Kdp; reflectivity Zh; and specific attenuation Ah. When compared with continental or coastal convection, tropical oceanic Zdr and Kdp values were more often of low magnitude (<0.5 dB, <0.3° km−1) and Zdr was lower for a given Kdp or Zh, consistent with observations of tropical oceanic DSDs being dominated by numerous, small, less-oblate drops. New X-, C-, and S-band R estimators were derived: R(Kdp), R(Ah), R(Kdp, ζdr), R(z, ζdr), and R(Ah, ζdr), which use linear versions of Zdr and Zh, namely ζdr and z. Except for R(Kdp), convective/stratiform partitioning was unnecessary for these estimators. All dual-polarization estimators outperformed updated R(z) estimators derived from the same dataset. The best-performing estimator was R(Kdp, ζdr), followed by R(Ah, ζdr) and R(z, ζdr). The R error was further reduced in an updated blended algorithm choosing between R(z), R(z, ζdr), R(Kdp), and R(Kdp, ζdr) depending on Zdr > 0.25 dB and Kdp > 0.3° km−1 thresholds. Because of these thresholds and the lack of hail, R(Kdp) was never used. At all wavelengths, R(z) was still needed 43% of the time during light rain (R < 5 mm h−1, Zdr < 0.25 dB), composing 7% of the total rain volume. As wavelength decreased, R(Kdp, ζdr) was used more often, R(z, ζdr) was used less often, and the blended algorithm became increasingly more accurate than R(z).

Published: December 2017

AbstractSpatiotemporal precipitation patterns were investigated on the western slopes of the central Andes Mountains by applying EOF and cluster analysis as well as the Weather Research and Forecasting (WRF) Model. In the semiarid catchment area in the highlands of Lima, Peru, the precipitation is assumed to be a cross-scale interplay of large-scale dynamics, varying sea surface temperatures (SSTs), and breeze-dominated slope flows. The EOF analysis was used to encompass and elucidate the upper-level circulation patterns dominating the transport of moisture. To delineate local precipitation regimes, a partitioning cluster analysis was carried out, which additionally should illustrate local effects such as the altitudinal gradient of the Andes. The results demonstrated that especially during the transition to the dry season, synoptic-scale circulation aloft controls the precipitation (correlation coefficients between 0.6 and 0.9), whereas in the remaining seasons the slope breezes due to the altitudinal gradient mainly determine the precipitation behavior. Further analysis with regard to the spatiotemporal precipitation variability revealed an inversion of the precipitation distribution along the elevational gradient within the study area, mainly during February (29%) and March (35%), that showed correlations with coastal SST patterns ranging between 0.56 and 0.67. WRF simulations of the underlying mechanisms disclosed that the large-scale circulation influences the thermally induced upslope flows while the strength of southeastern low-level winds related to the coastal SSTs caused a blocking of easterlies in the middle troposphere through a reduced anticyclonic effect. This interplay enables the generation of precipitation in the usually drier environment at lower elevations, which leads to a decrease in rainfall with increasing elevation.
A Framework for Convection and Boundary Layer Parameterization Derived from Conditional Filtering

Published: December 2017

AbstractA new theoretical framework is derived for parameterization of subgrid physical processes in atmospheric models; the application to parameterization of convection and boundary layer fluxes is a particular focus. The derivation is based on conditional filtering, which uses a set of quasi-Lagrangian labels to pick out different regions of the fluid, such as convective updrafts and environment, before applying a spatial filter. This results in a set of coupled prognostic equations for the different fluid components, including subfilter-scale flux terms and entrainment/detrainment terms. The framework can accommodate different types of approaches to parameterization, such as local turbulence approaches and mass flux approaches. It provides a natural way to distinguish between local and nonlocal transport processes and makes a clearer conceptual link to schemes based on coherent structures such as convective plumes or thermals than the straightforward application of a filter without the quasi-Lagrangian labels. The framework should facilitate the unification of different approaches to parameterization by highlighting the different approximations made and by helping to ensure that budgets of energy, entropy, and momentum are handled consistently and without double counting. The framework also points to various ways in which traditional parameterizations might be extended, for example, by including additional prognostic variables. One possibility is to allow the large-scale dynamics of all the fluid components to be handled by the dynamical core. This has the potential to improve several aspects of convection–dynamics coupling, such as dynamical memory, the location of compensating subsidence, and the propagation of convection to neighboring grid columns.
The Life Cycle of Spontaneously Generated Internal Waves
Authors: Shakespeare Callum J. , McC. Hogg Andrew 
Published: December 2017

AbstractRecent numerical modeling studies have suggested significant spontaneous internal wave generation near the ocean surface and energy transfers to and from these waves in the ocean interior. Spontaneous generation is the emission of waves by unbalanced, large Rossby number flows in the absence of direct forcing. Here, the authors’ previous work is extended to investigate where and how these waves exchange energy with the nonwave (mean) flow. A novel double-filtering technique is adopted to separate first the wave and nonwave fields, then the individual upward- and downward-propagating wave fields, and thereby identify the pathways of energy transfer. These energy transfers are dominated by the interaction of the waves with the vertical shear in the mean flow. Spontaneously generated waves are found to be oriented such that the downward-propagating wave is amplified by the mean shear. The internal waves propagate through the entire model depth while dissipating energy and reflect back upward. The now-upward-propagating waves have the opposite sign interaction with the mean shear and decay, losing most of their energy to the nonwave flow in the upper 500 m. Overall, in the simulations described here, approximately 30% of the wave energy is dissipated, and 70% is returned to the mean flow. The apparent preferential orientation of spontaneous generation suggests a potentially unique role for these waves in the ocean energy budget in uniformly drawing net energy from mean flow in the upper-ocean interior and transporting it to depth.
An Objective Method for Determining Ocean Mixed Layer Depth with Applications to WOCE Data
Authors: Huang Peng-Qi , Lu Yuan-Zheng , Zhou Sheng-Qi 
Published: December 2017

AbstractA new method is developed to identify the mixed layer depth (MLD) from individual temperature or density profiles. A relative variance profile is obtained that is the ratio between the standard deviation and the maximum variation of the temperature (density) from the sea surface, and the depth of the minimum relative variance is defined as the MLD. The new method is robust in finding the MLD under the influence of random noise (noise level ≤ 5%). A comparison with other available methods, which include the threshold (difference, difference interpolation, gradient, and hybrid methods) and objective (curvature and maximum angle methods) methods, is carried out using the World Ocean Circulation Experiment (WOCE) data. It is found that for a variety of depth sampling resolutions ranging from 0.04 to 25 dbar, the new method and the difference-interpolation method predict MLD values that are closer to the visually inspected ones than those by other methods. Moreover, the quality index (QI) of the MLD that is determined by the new method is the highest when compared with those of the available methods. Also, the application of the new method on the WOCE global dataset yields 94% of MLD values with , substantially higher than those (≤86%) of other methods. Ultimately, it is found that the new method determines very similar MLD values when applied to temperature or density profiles globally because it identifies the base of the mixed layer rather than the uppermost depth of the thermocline. This unique advantage makes the new method applicable in many cases, especially when the density profile is unavailable.
Evaluating a Training Program for Pharmacist Code Blue Response
Authors: Marlowe Karen F. , Woods Dennis D. 
Published: December 2017

Objective The purpose of this study was to determine if pharmacy-specific didactic and experiential education could increase pharmacists’ knowledge about code situations and their comfort level in responding to these events. Secondarily, we examined the impact of the program on pharmacists with various prior experience with cardiac arrest resuscitation (code blue events). Design Given the extensive use of medications during advanced cardiac life support, pharmacists working on resuscitation teams have a unique opportunity to improve patient care. If properly trained, pharmacists could potentially reduce medication errors, aid in medication preparation, and provide drug and compatibility information. However, a pharmacy-specific education program of this type is not currently available. Before beginning this project, a knowledge assessment and comfort level survey were administered to pharmacists to obtain baseline information about their knowledge of commonly used medications, hospital policies, and perceived comfort levels in performing resuscitation practices. The pharmacists attended an education session about these topics and were given an opportunity to practice medication preparation. Upon completion, each pharmacist repeated the knowledge assessment, a comfort survey, and a competency check list. Results Pharmacists’ performance on a written knowledge assessment improved by a mean of 3.5 ± 0.6 questions (P = 0.0001). Perceived comfort level also increased for several aspects of code involvement. Conclusion The data suggests that targeted education could increase pharmacists’ knowledge and comfort levels related to resuscitation efforts. Further investigation is required to determine the impact of the program on pharmacist performance during a resuscitation effort.

Published: December 2017

Purpose A major obstacle to successfully offering health care education programs is a lack of access to large numbers of people. To capture a large audience we proposed a pharmacy directed community health education and screening program using the hockey games at the University of Utah as the venue to educate a significant population. The objectives of this project were to evaluate the patrons’ perception of health care screening/education sessions offered at hockey games and to discover the number of patrons participating in the programs. Methods A variety of health care screening/education programs were offered at 12 hockey games on the University of Utah campus. Health care professionals were present to provide information, conduct screenings, and answer questions. All patrons who participated were asked to complete an anonymous survey to determine if the health sessions in this setting were beneficial. Results A total of 801 useable surveys were received from patrons who were screened and/or educated. Overall, the health care screening/education sessions were well perceived with 92% of the patrons rating the overall value of the sessions as “very good” or “excellent.” Patrons who were identified as being at risk for certain disease states were encouraged to follow-up with a physician. Conclusion The health care education/screening sessions provided at the University of Utah hockey games were successful based on the survey results and the number of patrons who participated. This program also demonstrated pharmacists can play a very effective role in designing and delivering health education to large numbers of patients.

Update on Resistance among Nosocomial Gram-Negative Pathogens to Extended-Spectrum Cephalosporins and Fluoroquinolones: Results of the Antimicrobial Resistance Management (ARM) Program
Authors: Gums John G. , Epstein Benjamin J. 
Published: December 2017

Objective To evaluate trends in antibiotic resistance among Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Pseudomonas aeruginosa isolates submitted to the Antimicrobial Resistance Management (ARM) program between 1990 and 2002. Design The ongoing Antimicrobial Resistance Management (ARM) program is a queriable Web-based surveillance system that tracks resistance patterns among U.S. inpatient and outpatient isolates. This report represents data from 285 institutions and over 17 million isolates. Using a Web-based analysis tool, antibiogram and sensitivity reports of E. coli, K. pneumoniae, P. mirabilis, and P. aeruginosa isolates were reviewed for resistance to extended-spectrum cephalosporins and fluoroquinolones. Setting 285 teaching and non-teaching U.S Hospitals nationwide. Results For E. coli, resistance was 3.2% to ciprofloxacin (n = 444,947), 5.4% to levofloxacin (n = 201,532), and 0.8% to cefotaxime (n = 107,394), ceftriaxone (n = 464,931), and cefepime (n = 81,980), respectively. K. pneumoniae isolate resistance was 4.6% to ciprofloxacin (n = 144,698), 4.5% to levofloxacin (n = 57,462), 1.9% to cefotaxime (n = 33,189), 2.0% to ceftriaxone (n = 145,328) and 1.9% to cefepime (n = 25,503). For P. mirabilis, resistance was 12.5% to ciprofloxacin (n = 83,186), 12.2% to levofloxacin (n = 35,277), 1.0% to cefotaxime (n = 18,802), 0.7% to ceftriaxone (83,652), and 2.3% to cefepime (n = 13,968). P. aeruginosa resistance was also higher for fluoroquinolones (only 65.2% of isolates were susceptible to ciprofloxacin) compared to extended-spectrum cephalosporins, with ceftazidime exhibiting the greatest antipseudomonal activity. Clinically significant regional variations in the activity of fluoroquinolones and cephalosporins were apparent. Conclusion Resistance to the fluoroquinolones is increasing dramatically, whereas the third generation cephalosporins remain inherently more active. P. aeruginosa exhibits the most formidable resistance pattern with neither the antipseudomonal cephalosporins nor fluoroquinolones representing acceptable monotherapy options. Given the association between fluoroquinolone resistance and extended-spectrum β-lactamase production, continued surveillance is vital to preserve the activity of existing therapies.
