RISAn Application of a Weakly Constrained 4DVAR to Satellite Data Assimilation and Heavy Rainfall Simulation
Publisher: American Meteorological Society
Abstract: In this paper a simple weakly constrained four-dimensional variational data assimilation (4DVAR) technique (W4DVAR) is used in the assimilation of retrieved satellite data for a heavy rainfall simulation. The W4DVAR and ...
Impact of Mesoscale Satellite Wind Data on Numerical Model Simulations: A Case Study
Publisher: American Meteorological Society
Abstract: Initialization of a comprehensive mesoscale numerical prediction model is investigated using actual low-level mesoscale satellite wind observations in a case study. Attention is focused on describing and understanding the ...
A Quantitative Study of Satellite Winds for Mesoscale Meteorology
Publisher: American Meteorological Society
Abstract: Quantitative characteristics and utility of mesoscale satellite winds are investigated for a low-level high spatial resolution data set obtained from a sequence of 6 min interval synchronous meteorological satellite images ...
An Observational Study of Mesoscale Convective Systems with Heavy Rainfall over the Korean Peninsula
Publisher: American Meteorological Society
Abstract: A heavy rainfall event induced by mesoscale convective systems (MCSs) occurred over the middle Korean Peninsula from 25 to 27 July 1996. This heavy rainfall caused a large loss of life and property damage as a result of ...
Retrieval of High-Resolution Wind Fields over the Southern Korean Peninsula Using the Doppler Weather Radar Network
Publisher: American Meteorological Society
Abstract: The performance of a radar network for retrieving high-resolution wind fields over South Korea is examined. The network consists of a total of 18 operational radars. All of the radars possess the Doppler capability and ...
Two Overlooked Biases of the Advanced Research WRF (ARW) Model in Geopotential Height and Temperature
Publisher: American Meteorological Society
Abstract: he authors have discovered two sizeable biases in the Weather Research and Forecasting (WRF) model: a negative bias in geopotential and a warm bias in temperature, appearing both in the initial condition and the forecast. ...
Critical Role of Northern Off-Equatorial Sea Surface Temperature Forcing Associated with Central Pacific El Niño in More Frequent Tropical Cyclone Movements toward East Asia
Publisher: American Meteorological Society
Abstract: bservational records reveal that the number of tropical cyclones (TCs) approaching East Asia in July?October is positively correlated with sea surface temperatures (SSTs) in the equatorial and northern off-equatorial central ...
Regional Climate Model Intercomparison Project for Asia
Publisher: American Meteorological Society
Abstract: Improving the simulation of regional climate change is one of the high-priority areas of climate study because regional information is needed for climate change impact assessments. Such information is especially important ...
Future Change in Tropical Cyclone Activity over the Western North Pacific in CORDEX-East Asia Multi-RCMs Forced by HadGEM2-AO
Publisher: American Meteorological Society
Abstract: AbstractFuture changes in tropical cyclone (TC) activity over the western North Pacific (WNP) are analyzed using four regional climate models (RCMs) within the Coordinated Regional Climate Downscaling Experiment (CORDEX) ...
