Issues of Soil Moisture Coupling in MM5: Simulation of the Diurnal Cycle over the FIFE Area
Publisher: American Meteorological Society
Abstract: This study evaluates the issues of soil moisture coupling on the partitioning of surface fluxes at the diurnal timescale over a mesoscale domain from the First International Satellite Land Surface Climatology Project Field ...
The Impact of a Hemispheric Circulation Regime on Fall Precipitation over North America
Publisher: American Meteorological Society
Abstract: While there is growing evidence that the main contribution to trends in U.S. precipitation occurs during fall, most studies of seasonal precipitation have focused on winter or summer. Here, the leading mode of fall ...
Growth and Decay of Error in a Numerical Cloud Model Due to Small Initial Perturbations and Parameter Changes
Publisher: American Meteorological Society
Abstract: The behavior of a numerical cloud model is investigated in terms of its sensitivity to perturbations with two kinds of lateral boundary conditions: 1) with cyclic lateral boundary conditions, the model is sensitive to many ...
Predictability of Mesoscale Rainfall in the Tropics
Publisher: American Meteorological Society
Abstract: A general framework has been developed to study the predictability of space?time averages of mesoscale rainfall in the tropics. A comparative ratio between the natural variability of the rainfall process and the prediction ...
A Possible Explanation for Low Correlation Dimension Estimates for the Atmosphere
Publisher: American Meteorological Society
Abstract: There have been numerous attempts to detect the presence of deterministic chaos by estimating the correlation dimension. The values of reported correlation dimension for various geophysical time series vary between 1.3 and ...
Observed Trends in Summertime Precipitation over the Southwestern United States
Publisher: American Meteorological Society
Abstract: In this paper, the authors evaluate the significance of multidecadal trends in seasonal-mean summertime precipitation and precipitation characteristics over the southwestern United States using stochastic, chain-dependent ...
A Streamflow and Water Level Forecasting Model for the Ganges, Brahmaputra, and Meghna Rivers with Requisite Simplicity
Publisher: American Meteorological Society
Abstract: AbstractA forecasting lead time of 5?10 days is desired to increase the flood response and preparedness for large river basins. Large uncertainty in observed and forecasted rainfall appears to be a key bottleneck in providing ...
