A Comparative Study on Precipitation Climatology and Interannual Variability in the Lower Midlatitude East Asia and Central Asia
Publisher: American Meteorological Society
Abstract: his study examines precipitation climatology and interannual variability in two regions in the lower midlatitude Asia to the east and west of the Tibetan Plateau, one located in monsoonal East Asia (the M region) and the ...
A Method for Identifying the Sensitive Areas in Targeted Observations for Tropical Cyclone Prediction: Conditional Nonlinear Optimal Perturbation
Publisher: American Meteorological Society
Abstract: Conditional nonlinear optimal perturbation (CNOP), which is a natural extension of the linear singular vector into the nonlinear regime, is proposed in this study for the determination of sensitive areas in adaptive ...
Impact of Microphysics Scheme Complexity on the Propagation of Initial Perturbations
Publisher: American Meteorological Society
Abstract: he study of evolution characteristics of initial perturbations is an important subject in four-dimensional variational data assimilation (4DVAR) and mesoscale predictability research. This paper evaluates the impact of ...
The Dependence of Daily and Hourly Precipitation Extremes on Temperature and Atmospheric Humidity over China
Publisher: American Meteorological Society
Abstract: AbstractPrecipitation extremes are expected to increase by 7% per degree of warming according to the Clausius?Clapeyron (CC) relation. However, this scaling behavior is inappropriate for high temperatures and short-duration ...
