The Impact of Microphysical Schemes on Hurricane Intensity and Track
During the past decade, both research and operational numerical weather prediction models [e.g. the Weather Research and Forecasting Model (WRF)] have started using more complex microphysical schemes originally developed for high-resolution cloud resolving models (CRMs) with 1-2 km or less horizontal resolutions. WRF is a next-generation meso-scale forecast model and assimilation system. It inc...
متن کاملMicrophysics Schemes Based on Dsd-parameter Constraints and Their Impact on Convective Storm Forecasts
It is clear that in order to accurately model convective scale events, we require the most accurate microphysical schemes possible. However this need for detailed microphysical parameterization must be balanced with the computational expense that such detailed parameterizations require. A new way of calculating the drop-size distribution (DSD) parameters in the single moment (hereafter SM) and ...
متن کاملAtmospheric Electricity and Cloud Microphysics
The terrestrial atmospheric electrical system covers a range of dimensional scales, from charged molecular clusters to convective cloud systems. Charge-exchange associated with thunderclouds leads to positive charge in the upper conductive regions of the atmosphere and a net negative charge on the planetary surface. In non-thunderstorm regions, a vertical ionic current flows, replenishing the a...
متن کاملThe Impact of Satellite-derived Winds on Gfdl Hurricane Model Forecasts
A series of experimental forecasts are performed to evaluate the impact of satellite-derived winds on numerical hurricane track predictions using the GFDL model. Over 100 cases are examined from 10 different storms covering 3 seasons (1996-1998), enabling us to account for the large case-to-case variability in the forecast results when assessing the wind impact. On average, assimilation of the ...
متن کاملThe Impact of Satellite Winds on Experimental GFDL Hurricane Model Forecasts
A series of experimental forecasts are performed to evaluate the impact of enhanced satellite-derived winds on numerical hurricane track predictions. The winds are derived from Geostationary Operational Environmental Satellite-8 (GOES-8) multispectral radiance observations by tracking cloud and water vapor patterns from successive satellite images. A three-dimensional optimum interpolation meth...
