RISMethod Development for Estimating Sensible Heat Flux over the Tibetan Plateau from CMA Data
Publisher: American Meteorological Society
Abstract: To clarify the thermal forcing of the Tibetan Plateau, long-term coarse-temporal-resolution data from the China Meteorological Administration have been widely used to estimate surface sensible heat flux by bulk methods in ...
Validation of a Dual-Pass Microwave Land Data Assimilation System for Estimating Surface Soil Moisture in Semiarid Regions
Publisher: American Meteorological Society
Abstract: This study examines the capability of a new microwave land data assimilation system (LDAS) for estimating soil moisture in semiarid regions, where soil moisture is very heterogeneous. This system assimilates the Advanced ...
Improving the Noah Land Surface Model in Arid Regions with an Appropriate Parameterization of the Thermal Roughness Length
Publisher: American Meteorological Society
Abstract: Daytime land surface temperatures in arid and semiarid regions are typically not well simulated in current land surface models (LSMs). This study first evaluates the importance of parameterizing the thermal roughness length ...
Observed Coherent Trends of Surface and Upper-Air Wind Speed over China since 1960
Publisher: American Meteorological Society
Abstract: revious studies indicated that surface wind speed over China declined during past decades, and several explanations exist in the literature. This study presents long-term (1960?2009) changes of both surface and upper-air ...
Improving Predictions of Water and Heat Fluxes by Assimilating MODIS Land Surface Temperature Products into the Common Land Model
Publisher: American Meteorological Society
Abstract: Four data assimilation scheme combinations derived from two strategies and two optimization algorithms [the ensemble Kalman filter (EnKF) and the shuffled complex evolution method developed at The University of Arizona ...
Experimental Study on Mechanical Properties and Failure Criteria of Self-Compacting Concrete under Biaxial Tension-Compression
Publisher: American Society of Civil Engineers
Abstract: In order to explore the basic mechanical properties of self-compacting concrete, ordinary concrete, lightweight aggregate concrete, self-compacting ordinary concrete, and self-compacting lightweight aggregate concrete were ...
On the Climatology and Trend of the Atmospheric Heat Source over the Tibetan Plateau: An Experiments-Supported Revisit
Publisher: American Meteorological Society
Abstract: Atmospheric heating over the Tibetan Plateau (TP) enhances the Asian summer monsoon. This study presents a state-of-the-art estimate of the heating components and their total over the TP, with the aid of high-accuracy ...
Estimation of Daily Mean Photosynthetically Active Radiation under All-Sky Conditions Based on Relative Sunshine Data
Publisher: American Meteorological Society
Abstract: hotosynthetically active radiation (PAR) is absorbed by plants to carry out photosynthesis. Its estimation is important for many applications such as ecological modeling. In this study, a broadband transmittance scheme for ...

Severe Historical Droughts Carved on Rock in the Yangtze
Publisher: American Meteorological Society
Abstract: The White Crane Ridge (WCR) Rock Fish, now submerged under the backwater of the Three Gorges Reservoir in the Yangtze River, are affirmed as one of the earliest hydrologic observations ever made in any large river in the ...
