The TRMM Multisatellite Precipitation Analysis (TMPA): Quasi-Global, Multiyear, Combined-Sensor Precipitation Estimates at Fine Scales Tập 8 Số 1 - Trang 38-55 - 2007

Abstract The Tropical Rainfall Measuring Mission (TRMM) Multisatellite
Precipitation Analysis (TMPA) provides a calibration-based sequential scheme for
combining precipitation estimates from multiple satellites, as well as gauge
analyses where feasible, at fine scales (0.25° × 0.25° and 3 hourly). TMPA is
available both after and in real time, based on calibration by the TRMM Combined

The Influence of Mechanical and Thermal Forcing by the Tibetan Plateau on Asian Climate Tập 8 Số 4 - Trang 770-789 - 2007
Wu, Gx, Guoxiong, Xingcai Liu, Ym, Yimin, Yingying Wang, TM, Tongmei, Wan Norhaniza Wan Hasan, RJ, Rijin, Xiaoyu Liu, Li Li, Wp., Wei Ping, ZZ, Zaizhi, Yongjun Zhang, Q, Qiong Qiong, Bei Feng, AM, Anmin, Liang Liang, Xy, Xiaoyun
Abstract This paper attempts to provide some new understanding of the mechanical
as well as thermal effects of the Tibetan Plateau (TP) on the circulation and
climate in Asia through diagnosis and numerical experiments. The air column over
the TP descends in winter and ascends in summer and regulates the surface Asian
monsoon flow. Sensible heating on the sloping lateral surfaces appears from the

Impact of a Statistical Bias Correction on the Projected Hydrological Changes Obtained from Three GCMs and Two Hydrology Models Tập 12 Số 4 - Trang 556-578 - 2011
Stefan Hagemann, Chen Cui, Jan O. Haerter, Jens Heinke, Dieter Gerten, C. Piani
Abstract Future climate model scenarios depend crucially on the models’ adequate
representation of the hydrological cycle. Within the EU integrated project Water
and Global Change (WATCH), special care is taken to use state-of-the-art climate
model output for impacts assessments with a suite of hydrological models. This
coupling is expected to lead to a better assessment of changes in the
hydrolog... hiện toàn bộ
Meteorological Causes of the Secular Variations in Observed Extreme Precipitation Events for the Conterminous United States Tập 13 Số 3 - Trang 1131-1141 - 2012
Kenneth E. Kunkel, David R. Easterling, David A. R. Kristovich, B. Gleason, Leslie A. Stoecker, Rebecca Smith
Abstract Daily extreme precipitation events, exceeding a threshold for a
1-in-5-yr occurrence, were identified from a network of 935 Cooperative Observer
stations for the period of 1908–2009. Each event was assigned a meteorological
cause, categorized as extratropical cyclone near a front (FRT), extratropical
cyclone near center of low (ETC), tropical cyclone (TC), mesoscale convective
system (MCS... hiện toàn bộ
Examining Rapid Onset Drought Development Using the Thermal Infrared–Based Evaporative Stress Index Tập 14 Số 4 - Trang 1057-1074 - 2013
Jason A. Otkin, Martha C. Anderson, Christopher Hain, I. E. Mladenova, Jeffrey B. Basara, Mark Svoboda
AbstractReliable indicators of rapid drought onset can help to improve the
effectiveness of drought early warning systems. In this study, the evaporative
stress index (ESI), which uses remotely sensed thermal infrared imagery to
estimate evapotranspiration (ET), is compared to drought classifications in the
U.S. Drought Monitor (USDM) and standard precipitation-based drought indicators
for several... hiện toàn bộ
Characteristics of Precipitating Convective Systems in the South Asian Monsoon Tập 12 Số 1 - Trang 3-26 - 2011
Ulrike Romatschke, Robert A. Houze
AbstractEight years of Tropical Rainfall Measuring Mission (TRMM) Precipitation
Radar (PR) data show how convective systems of different types contribute to
precipitation of the South Asian monsoon. The main factor determining the amount
of precipitation coming from a specific system is its horizontal size.
Convective intensity and/or number of embedded convective cells further enhance
its precipi... hiện toàn bộ
Rainfall and Water Resources Variability in Sub-Saharan Africa during the Twentieth Century Tập 10 Số 1 - Trang 41-59 - 2009
Declan Conway, A. Persechino, Sandra Ardoin‐Bardin, Hamisai Hamandawana, Claudine Dieulin, Gil Mahé
Abstract River basin rainfall series and extensive river flow records are used
to characterize and improve understanding of spatial and temporal variability in
sub-Saharan African water resources during the last century. Nine major
international river basins were chosen for examination primarily for their
extensive, good quality flow records. A range of statistical descriptors
highlight the substa... hiện toàn bộ
Modeling Evapotranspiration during SMACEX: Comparing Two Approaches for Local- and Regional-Scale Prediction Tập 6 Số 6 - Trang 910-922 - 2005
Hongbo Su, Matthew F. McCabe, Eric F. Wood, Zhongbo Su, John H. Prueger
Abstract The Surface Energy Balance System (SEBS) model was developed to
estimate land surface fluxes using remotely sensed data and available
meteorology. In this study, a dual assessment of SEBS is performed using two
independent, high-quality datasets that are collected during the Soil
Moisture–Atmosphere Coupling Experiment (SMACEX). The purpose of this comparison
is twofold. First, using high... hiện toàn bộ
Hydrologic Sensitivities of Colorado River Runoff to Changes in Precipitation and Temperature* Tập 13 Số 3 - Trang 932-949 - 2012
J. A. Vano, Tapash Das, Dennis P. Lettenmaier
Abstract The Colorado River is the primary water source for much of the rapidly
growing southwestern United States. Recent studies have projected reductions in
Colorado River flows from less than 10% to almost 50% by midcentury because of
climate change—a range that has clouded potential management responses. These
differences in projections are attributable to variations in climate model
