Mesoscale Banded Precipitation
Precipitation frequently falls and accumulates in discrete bands with accumulations that vary markedly over short distances. This module examines several mechanisms that result in mesoscale banded precipitation, focusing primarily on processes at work in midlatitude cyclones. The module starts with a review of the Norwegian and conveyor belt cyclone models. Then several banding processes are examined in detail, including deformation/frontogenesis, the Trowal (Trough of Warm Air Aloft), frontal merger, CSI/slantwise convection, and melting/evaporation-induced circulations. The module concludes ...

The module concludes with discussions of the representation of banded precipitation by NWP models and the detection of banded precipitation with satellite sensors.

Unit Hydrograph Theory
The role of unit hydrograph theory in the flood prediction process is to provide an estimate of streamflow given the precipitation. A unit hydrograph shows the temporal change in flow, or discharge, per unit of runoff from excess precipitation. In other words, the unit hydrograph shows how the flow of a stream will be affected over time by the addition of one unit of runoff. This module offers a thorough introduction to the use of unit hydrographs and the application of unit hydrograph theory in flood prediction. Through use of rich illustrations, animations, and interactions, this module expl ...

The Global Energy and Water Cycle Experiment (GEWEX) of the World Climate Research Programme (WCRP), sponsored by the World Meteorological Organization (WMO), the International Council for Science (ICSU), and the Intergovernmental Oceanographic Commission (IOC) of the United Nations Educational, Scientific and Cultural Organization (UNESCO), has amassed an outstanding record of accomplishments during the first phase of its planned program. From bringing hydrology, land surface, and atmospheric sciences communities together, to showing the importance of understanding soil moisture/atmosphere and cloud/radiation interactions and their parameterization within prediction models, GEWEX has been on the leading edge of science since its inception. Pulling together the global data sets necessary for validation of our predictive models and fostering direct applications with water resources user groups have also provided significant advances in climate research. This brochure provides just a sample of the numerous accomplishments that GEWEX has achieved during its build-up phase (Phase I). This prepares the stage for many more advances in Phase II, when the community will exploit the new fleet of environmental satellites and build upon the newly implemented model upgrades developed in Phase I.

Forecasting Radiation Fog
This is the second module in the Mesoscale Meteorology Primer series. This module starts with a forecast scenario that occurs during a winter radiation fog event in the Central Valley of California. After that, a conceptual section covers the physical processes of radiation fog through its life cycle. Operational sections addressing fog detection and forecasting conclude the module
