Modern Meteorological Computing Resources—the Maryland Experience
Publisher: American Meteorological Society
Abstract: The Department of Meteorology at the University of Maryland is developing one of the first computer. systems in meteorology to take advantage of the new networked computer architecture that has been made possible by recent ...
Estimates of Root-Mean-Square Random Error for Finite Samples of Estimated Precipitation
Publisher: American Meteorological Society
Abstract: The random errors contained in a finite set E of precipitation estimates result from both finite sampling and measurement?algorithm effects. The expected root-mean-square random error associated with the estimated average ...
Investigating Error Metrics for Satellite Rainfall Data at Hydrologically Relevant Scales
Publisher: American Meteorological Society
Abstract: This paper addresses the following open question: What set of error metrics for satellite rainfall data can advance the hydrologic application of new-generation, high-resolution rainfall products over land? The authors? ...
A Stochastic Model of Cumulus Clumping
Publisher: American Meteorological Society
Abstract: Observations show that cumulus clouds often occur in long-lived mesoscale groups, or clumps. Five possible explanations of clumping are surveyed. The ?mutual protection hypothesis,? that clumps occur because cumulus clouds ...
Design Issues in Nearly Real-Time Meteorological-Data Systems at Local Sites
Publisher: American Meteorological Society
Abstract: A scheme developed at the University of Maryland is described to illustrate the high-level design decisions which must be made in order to fully utilize the asynchronous character-oriented data transmitted over the Domestic ...
Transfer of Satellite Rainfall Uncertainty from Gauged to Ungauged Regions at Regional and Seasonal Time Scales
Publisher: American Meteorological Society
Abstract: Hydrologists and other users need to know the uncertainty of the satellite rainfall datasets across the range of time?space scales over the whole domain of the dataset. Here, ?uncertainty? refers to the general concept of ...
The Supercooled Warm Rain Process and the Specification of Freezing Precipitation
Publisher: American Meteorological Society
Abstract: About 30% of freezing precipitation cases are observed to occur in a subfreezing atmosphere (contrary to the classical melting ice model). We explain these cases with the concept of the ?supercolled warm rain process? ...
Entrainment and Detrainment in a Simple Cumulus Cloud Model
Publisher: American Meteorological Society
Abstract: A cumulus cloud's size, shape and internal properties can be predicted, provided that the rate of entrainment is determined by a suitable entrainment parameterization theory. A cumulus cloud model based on such a theory ...
Statistical Modeling of Extreme Precipitation with TRMM Data
Publisher: American Meteorological Society
Abstract: AbstractThis paper improves upon an existing extreme precipitation monitoring system that is based on the Tropical Rainfall Measuring Mission (TRMM) daily product (3B42) using new statistical models. The proposed system ...
