Drought is a major constraint of forest productivity and tree growth across diverse habitat types. In this study, we investigated the drought responses of four conifer species growing within two locations of differing elevation and climatic conditions in northern Mexico. Two species were selected at a mesic site (Cupressus lusitanica Mill., Abies durangensis Martínez) and the other two species were sampled at a xeric site (Pinus engelmannii Carr., Pinus cembroides Zucc.). Using a dendrochronological approach, we correlated the radial-growth series of each species and the climatic variables. All study species positively responded to wet-cool conditions during winter and spring. Despite the close proximity of species at a mesic site, A. durangensis had high responsiveness to hydroclimatic variability, but C. lusitanica was not responsive. At the xeric site, P. engelmannii and P. cembroides were very responsive to drought severity, differentiated only by the longer time scale of the response to accumulated drought of P. engelmannii. The responsiveness to hydroclimate and drought of these tree species seems to be modulated by site conditions, or by the functional features of each species that are still little explored. These findings indicate that differentiating between mesic and xeric habitats is a too coarse approach in diverse forests with a high topographic heterogeneity.

Located in northwest Baja California, Mexico, the Guadalupe River Basin is situated in a semiarid region where periods of drought pose serious economic, social and environmental concerns. The study area has highly variable climate, with mean annual precipitation ranging from less than 12 mm to over 750 mm a year across the basin, and with most of the annual precipitation occurring during the autumn and winter seasons. To quantify the frequency and severity of meteorological droughts at the local (watershed) scale, this study investigates seasonal and annual precipitation data from 34 sites in northwest Baja California. Along with the analysis of precipitation climatology and interannual variability, El Niño/Southern Oscillation (ENSO) and related Pacific Ocean sea surface temperature (SST) patterns are shown to be potential predictors of seasonal precipitation. Analysis of precipitation variability at seasonal and annual time scales is performed using the standardized precipitation index (SPI) methodology, and annual, seasonal, and ENSOconditioned precipitation frequency analyses are executed using the regional L-moment algorithm. The SPI and regional rainfall drought frequency estimates developed in this study may be useful for monitoring meteorological droughts and could serve as critical components of a comprehensive drought management plan. Furthermore, the methods applied in this study may be transferred to other semi-arid locations to mitigate drought risk and, potentially, impacts of drier conditions in the 21st century.

“…This helped define the areal domain in which to focus a more in-depth evaluation. The Climate Explorer model allows efficient data acquisition and processing of a variety of statistical procedures including lead/lag correlation analysis (van Oldenborgh and Burgers, 2005) and stores numerous hydrologic data sets for online processing. The TNI Ł was uploaded into the Climate Explorer model and correlated with Apr-Sep HCDN streamflow and 1 Apr NRCS SWE, which are both built into the KMNI model, for all stations in the western US during 1950-1988 and 1981-2004 respectively. After the general signal extent was determined, 68 stream gauges taken from the preliminary analysis with the TNI Ł were selected and updated to 2004 using historic USGS streamflow data.…”

Abstract:This research investigates large-scale climate features affecting inter-annual hydrologic variability of streams flowing into Upper Klamath Lake (UKL), Oregon, USA. UKL is an arid, mountainous basin located in the rain shadow east of the crest of the Cascade Mountains in the northwestern United States. Developing accurate statistical models for predicting spring and summer seasonal streamflow volumes for UKL is difficult because the basin has complex hydrology and a high degree of topographic and climatologic variability. In an effort to reduce streamflow forecast uncertainty, six large-scale climate indices-the Pacific North American Pattern, Southern Oscillation Index, Pacific Decadal Oscillation (PDO), Multivariate El Niño-Southern Oscillation Index, Niño 3Ð4, and a revised Trans-Niño Index (TNI)-were evaluated for their ability to explain inter-annual variation of the major hydrologic inputs into UKL.The TNI is the only index to show significant correlations during the current warm phase of the PDO. During the warm PDO phase (1978-present), the averaged October through December TNI is strongly correlated with the subsequent April through September streamflow (r D 0Ð7) and 1 April snow water equivalent (r D 0Ð6). Regional analysis shows that this climate signal is not limited to UKL but is found throughout the northwestern United States.Incorporating the TNI variable into statistical streamflow prediction models results in standard errors of forecasts issued on the first of February and earlier that are 7-10% smaller than those for the models without the TNI. This, coupled with other enhancements to the statistical models, offers a significant increment of improvement in forecasts used by water managers.
