RISMechanisms for the Dipolar Patterns of Rainfall Variability over Large Islands in the Maritime Continent Associated with the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: Before the eastward-propagating rainy envelope of a Madden–Julian oscillation (MJO) arrives at the Maritime Continent (MC), some islands in the MC experience dipolar patterns of rainfall variability with opposite signs of ...
Why Precipitation Is Mostly Concentrated over Islands in the Maritime Continent
Publisher: American Meteorological Society
Abstract: High-resolution observations and regional climate model simulations reveal that precipitation over the Maritime Continent is mostly concentrated over islands. Analysis of the diurnal cycles of precipitation and winds ...
Normal Modes of a Global Nonhydrostatic Atmospheric Model
Publisher: American Meteorological Society
Abstract: Anticipating use of a very high resolution global atmospheric model for numerical weather prediction in the future without a traditional hydrostatic assumption, this article describes a unified method to obtain the normal ...
The Effect of Grid Spacing and Domain Size on the Quality of Ensemble Regional Climate Downscaling over South Asia during the Northeasterly Monsoon
Publisher: American Meteorological Society
Abstract: The performance of an ensemble-based dynamical regional climate downscaling system is evaluated over southern Asia in a northeasterly monsoon season for different choices in grid spacing and domain size. A seven-member ...
Reinitialized versus Continuous Simulations for Regional Climate Downscaling
Publisher: American Meteorological Society
Abstract: The methodology for dynamical climate downscaling is studied using the second-generation regional climate model (RegCM2). The question addressed is, in order to simulate high-resolution details as accurately as possible, ...
Interactions among ENSO, the Monsoon, and Diurnal Cycle in Rainfall Variability over Java, Indonesia
Publisher: American Meteorological Society
Abstract: Using a high-resolution regional climate model?the Abdus Salam International Centre for Theoretical Physics Regional Climate Model version 3 (RegCM3)?and station and satellite observations, the authors have studied the ...
A Global Nonhydrostatic Semi-Lagrangian Atmospheric Model with Orography
Publisher: American Meteorological Society
Abstract: A global nonhydrostatic semi-implicit semi-Lagrangian (SISL) atmospheric model with orography has been developed. The height-based terrain-following σz coordinate of Gal-Chen and Somerville is used to incorporate the ...
Diurnal Cycle in Different Weather Regimes and Rainfall Variability over Borneo Associated with ENSO
Publisher: American Meteorological Society
Abstract: he interannual variability of precipitation over the island of Borneo in association with El Niño?Southern Oscillation (ENSO) has been studied by using the Global Precipitation Climatology Centre (GPCC) gridded rain gauge ...
A Global Nonhydrostatic Semi-Lagrangian Atmospheric Model without Orography
Publisher: American Meteorological Society
Abstract: A semi-Lagrangian semi-implicit finite-difference nonhydrostatic global atmospheric model on a flat terrain has been developed. Starting from the initialized ECMWF analysis of 0000 UTC 15 January 1979, a series of 5-day ...
Mechanisms for Torrential Rain Associated with the Mei-Yu Development during SCSMEX 1998
Publisher: American Meteorological Society
Abstract: A case of torrential precipitation associated with the mei-yu front, an Asian summer monsoon system east of the Tibetan Plateau, is studied using the coupled fifth-generation Pennsylvania State University?NCAR Mesoscale ...
