title: NOAA/WDS Paleoclimatology - North American Monsoon 470-Year Subannual Precipitation Index Reconstructions

description: The North American monsoon is a major focus of modern and paleoclimate research, but relatively little is known about interannual- to decadal-scale monsoon moisture variability in the pre-instrumental era. This study draws from a new network of subannual tree-ring latewood width chronologies and presents a 470-year reconstruction of monsoon (June-August) standardized precipitation for southwestern North America. Comparison with an independent reconstruction of cool-season (October-April) standardized precipitation indicates that southwestern decadal droughts of the last five centuries were characterized not only by cool-season precipitation deficits but also by concurrent failure of the summer monsoon. Monsoon drought events identified in the past were more severe and persistent than any of the instrumental era. The relationship between winter and summer precipitation is weak, at best, and not time stable. Years with opposing-sign seasonal precipitation anomalies, as noted by other studies, were anomalously frequent during the mid to late 20th century.
description: Southwestern North America monsoon (June-August) precipitation reconstruction, based on a multispecies tree ring latewood width chronology network. Target region for the reconstructions is monsoon region 2 (NAM2), as defined by the North American Monsoon Experiment Forecast Forum (30-35N, 107.75-113.25W). Monthly precipitation data are from a 0.5 degree gridded product developed by NOAA. NAM2 grid point data were averaged to produce time series of monthly precipitation and correlation analysis was used to assess relationships to the subannual tree-ring chronologies. October-April (cool season) and June-August (monsoon) were selected as the seasons for reconstruction, and precipitation totals for these seasons were converted to standardized precipitation indices (SPI).

title: NOAA/WDS Paleoclimatology - Makassar Strait 14KYr Foraminiferal Mg/Ca SST and d18Osw

description: High sea surface temperatures in the western Pacific warm pool fuel atmospheric convection and influence tropical climate. This region also hosts the Indonesian throughflow, the network of currents through which surface and thermocline waters are transported from the western equatorial Pacific Ocean into the Indian Ocean. Here we show, using records of the d18O and Mg/Ca of planktonic foraminifera from eight sediment cores, that from about 10,000 to 7,000 years ago, sea surface temperatures in the western sector of the western Pacific warm pool were about 0.5°C higher than during pre-industrial times.  We also find that about 9,500 years ago, when the South China and Indonesian seas were connected by rising sea level, surface waters in the Makassar Strait became relatively fresher. We suggest that the permanent reduction of surface salinity initiated the enhanced flow at lower, thermocline depths seen in the modern Indonesian throughflow. However, the uniformly warm sea surface temperatures found upstream and downstream of the Indonesian throughflow indicate that the early Holocene warmth in this region was not directly related to reduced heat transport by the throughflow that may have resulted from surface freshening of the Makassar Strait. Instead, we propose that the elevated temperatures were the result of a westward shift or expansion of the boundaries of the western Pacific warm pool.

title: NOAA/WDS Paleoclimatology - Villanueva - Barranca de Amealco - TAMU - ITRDB MEXI047

description: Ancient Montezuma baldcypress (Taxodium mucronatum) trees found in Barranca de Amealco, Queretaro, have been used to develop a 1,238-year treering chronology that is correlated with precipitation, temperature, drought indices, and crop yields in central Mexico. This chronology has been used to reconstruct the spring-early summer soil moisture balance over the heartland of the Mesoamerican cultural province, and is the first exactly dated, annually resolved paleoclimatic record for Mesoamerica spanning the Late Classic, Post Classic, Colonial, and modern eras. The reconstruction indicates that the Terminal Classic drought extended into central Mexico, supporting other sedimentary and speleothem evidence for this early 10th century drought in Mesoamerica. The reconstruction also documents severe and sustained drought during the decline of the Toltec state (1149-1167) and during the Spanish conquest of the Aztec state (1514-1539), providing a new precisely dated climate framework for Mesoamerican cultural change.

title: NOAA/WDS Paleoclimatology - Florida Straits 41KYr Foraminiferal Stable Isotope Data

description: The waters passing through the Florida Straits today reflect both the western portion of the wind-driven subtropical gyre and the northward flow of the upper waters which cross the equator, compensating North Atlantic Deep Water export as part of the large-scale Atlantic meridional overturning circulation. It has been postulated from various lines of evidence that the overturning circulation was weaker during the Younger Dryas cold event of the last deglaciation. We show here that the contrast in the oxygen isotopic composition of benthic foraminiferal tests across the Florida Current is reduced during the Younger Dryas. This most likely reflects a decrease in the density gradient across the channel and a decrease in the vertical shear of the Florida Current. This reduced shear is consistent with the postulated reduction in the Atlantic meridional overturning circulation. We find that the onset of this change in density structure and flow at the start of the Younger Dryas is very abrupt, occurring in less than 70 years.
description: Foraminiferal stable isotope data from 6 sediment cores collected 
from the Florida Straits. 

Some of the stable isotope data has been previously published 
in Lynch-Stieglitz et al. (2009) and Came et al. (2007, 2008), 
and is presented here along with additional isotopic data and 
up to date age models based on the dates listed in Table 2.

title: NOAA/WDS Paleoclimatology - Gray - Fremont Lake - PSME - ITRDB WY045

description: In western North America, snowpack has declined in recent decades, and further losses are projected through the 21st century. Here, we evaluate the uniqueness of recent declines using snowpack reconstructions from 66 tree-ring chronologies in key runoff-generating areas of the Colorado, Columbia, and Missouri River drainages. Over the past millennium, late 20th century snowpack reductions are almost unprecedented in magnitude across the northern Rocky Mountains and in their north-south synchrony across the cordillera. Both the snowpack declines and their synchrony result from unparalleled springtime warming that is due to positive reinforcement of the anthropogenic warming by decadal variability. The increasing role of warming on large-scale snowpack variability and trends foreshadows fundamental impacts on streamflow and water supplies across the western United States.

title: NOAA/WDS Paleoclimatology - Nino3.4 SST 460 Year Reconstructions

description: In this study we compare three newly developed independent NINO3.4 sea surface temperature (SST) reconstructions using data from (1) the central Pacific (corals), (2) the TexMex region of the USA (tree rings) and (3) other regions in the Tropics (corals and an ice core) which are teleconnected with central Pacific SSTs in the 20th century. Although these three reconstructions are strongly calibrated and well verified, inter-proxy comparison shows a significant weakening in interproxy coherence in the 19th century. This breakdown in common signal could be related to insufficient data, dating errors in some of the proxy records or a breakdown in El Nino–Southern Oscillation's (ENSO's) influence on other regions. However, spectral analysis indicates that each reconstruction portrays ENSO-like spectral properties. Superposed epoch analysis also shows that each reconstruction shows a generally consistent 'El Nino-like' response to major volcanic events in the following year, while during years T+4 to T+7 'La Nina-like' conditions prevail. These results suggest that each of the series expresses ENSO-like 'behaviour', but this 'behaviour' does not appear to be spatially or temporally consistent. This result may reflect published observations that there appear to be distinct 'types' of ENSO variability depending on location within the tropical Pacific. Future work must address potential dating issues within some proxies (i.e. sampling of multiple coral heads for one location) as well as assessing the time stability of local climate relationships with central Pacific SSTs. More emphasis is needed on sampling new and extending old coral proxy records from the crucial central and eastern tropical Pacific region.
description: Nino3.4 SST reconstructions based on a variety of proxy data, utilizing 3 reconstruction methodologies, for the core ENSO region in the central and eastern tropical Pacific, and for other tropical regions displaying teleconnected ENSO responses. The first region is labeled the 'centre of action' (COA), located in the central and eastern Pacific, where SSTs are positively correlated with NINO3.4 SSTs. The second region is the 'teleconnection' (TEL) region covering all other tropical areas where SSTs are either inversely (e.g. Indonesia to Tonga) or positively (e.g. Indian Ocean) correlated with NINO3.4 SSTs. Independent reconstructions of annual NINO3.4 SSTs were developed for the COA and TEL regions, using three approaches: (1) composite plus regression, (2) principal component regression, and (3) regularised expectation maximisation.
