Diurnal and seasonal variations in surface fluxes and boundary layer depth are examined. The boundary layer is compared over the ocean, humid, and dry tropics, including its role in dispersing chemicals and aerosols. Boundary layer clouds are examined in terms of their connection to sub-cloud layer properties. Comparisons are made between heat and moisture transport under a variety of convective modes such as mesoscale convective system ...
African Easterly Waves
This module describes characteristics of African easterly waves including horizontal and vertical structure, evolution, speed, frequency, methods of tracking, and their downstream transformation over the Atlantic, Caribbean, and East Pacific. Mechanisms for wave formation are presented. Also explored are differences between waves that develop into tropical cyclones and those that do not. The final sections focus on extratropical interactions and variability of easterly waves.
Deformation Zone Distribution
The distribution of vorticity centres along an axis of maximum winds follows a fairly predictable pattern based on the characteristics of the flow. By diagnosing these characteristics, the meteorologist is able to quickly deduce the location and relative intensities of the associated vorticity centres as well as the relative sizes of the associated circulations. This information is summarized within the shape and orientation of the associated deformation zones. The deformation zones in turn reveal important details regarding feature motion and thermal advection and thus their diagnosis should ...
GOES-R Series Faculty Virtual Course: Advanced Baseline Imager

S-290 Unit 12: Gauging Fire Behavior and Guiding Fireline Decisions
S-290 Unit 12: Gauging Fire Behavior and Guiding Fireline Decisions examines how fire behavior is evaluated and changes are identified, and how these changes affect fireline decisions. Topics in this module build upon information covered in previous units and applies it to calculating safety zones, evaluating limitations of suppression efforts, and using tools used to predict fire behavior. The FireLine Assessment MEthod (FLAME) is introduced, and cases are provided to allow learners to apply this method to typical fireline conditions. This module is part of the Intermediate Wildland Fire Beha ...
Snowmelt Processes: International Edition
Snowmelt is an integral component of the hydrologic forecasting process in many parts of the world. Here, we examine the influences of environmental conditions on snowfall distribution, snowpack structure, snowpack-environment energy exchange, and finally, the rate and amount of snowmelt itself. The fate of snowmelt water after it reaches the ground is also explored.

Winds in the Marine Boundary Layer: A Forecaster's Guide
This module is intended for experienced forecasters moving from a land-based area to a coastal or Great Lakes region where both over-land and over-water forecast areas exist. This module highlights the differences between marine boundary layer and terrestrial boundary layer winds. The experienced forecaster is relatively familiar with the boundary layer over land and the associated implications for the wind field. Using this as a base, the module compares this known quantity with the lesser-known processes that occur in the marine boundary layer. Three major topics that influence marine bounda ...
