The Weather Research and Forecast (WRF) model was run over South-east Australia from 1985 through 2008. The model used the following physics schemes: WRF Single Moment 5-class microphysics scheme; Rapid Radiative Transfer Model longwave radiation scheme; Dudhia shortwave radiation scheme; Monin-Obukhov surface layer similarity; Noah land-surface scheme; Yonsei University boundary layer scheme a...

Using the daily temperature data from meteorological stations in Yunnan province and Guizhou 2000 to 2019, NCEP/NCAR re-analyzed on a basis, analyzed temporal spatial characteristics of extreme events study area. Research shows that region is warming; index different tendency, all have abrupt changes; maximum monthly heat persistence will continue increase future, number cold night days are str...

Abstract Performance of global climate models (GCMs) is strongly affected by the cumulus parameterization (CP) used. Similar to approach in GFDL AM4, a double-plume CP, which unifies deep and shallow convection one framework, implemented tested NCAR Community Atmospheric Model version 5 (CAM5). Based on University Washington (UW) scheme, an additional plume was added represent convection. The p...

From a mathematical point of view the fundamental challenge of computational fluid dynamics arises from nonlinear terms in the governing dynamical equations, of which the prototype is the flow velocity ~u and its advection (~u· ~ ∇)~u. It is commonly known that the most accurate and efficient method to compute the gradient (~ ∇) part is the spectral method, in which ~u(~x) is approximated at ea...

drought monitoring, which is a crucial component of drought management, aims to provide information that enables and supports people and organizations to take actions to reduce potential drought-related impact and damage. we usually tend to focus on drought when it is occurring and to react when crises strike. however, recent experiences and developments on drought knowledge are encouraging soc...
