Nowcasting for Aviation in Africa
Nowcasting for Aviation in Africa summarizes techniques and best practices for developing area-specific forecasts at very short (0-6 hour) timescales. This 1-hour lesson presents a case study focused on interpreting threats and communicating correct warning information for a weather event affecting multiple airports in Gauteng Province, South Africa. In completing the lesson, the learner will assess the state of the atmosphere, develop a nowcast, monitor conditions, and update/create appropriate nowcast products for aviation stakeholders.

Mountain Waves and Downslope Winds
Mountain waves form above and downwind of topographic barriers and frequently pose a serious hazard to mountain aviation because of strong-to-extreme turbulence. This foundation module describes the features of mountain waves and explores the conditions under which they form. Like other foundation modules in the Mesoscale Primer, this module starts with a forecast scenario and concludes with a final exam. Rich graphics, audio narration, and frequent interactions enhance the presentation.

Principles of Convection II: Using Hodographs
This lesson provides a basic understanding of how to plot and interpret hodographs, with application to convective environments. Most of the material previously appeared in the CD lesson, Anticipating Convective Storm Structure and Evolution, developed with Dr. Morris Weisman. Principles of Convection II: Using Hodographs includes a concise summary for quick reference and a final exam to test your knowledge. The lesson comes with audio narration, rich graphics, and a companion print version.

Principles of Convection III: Shear and Convective Storms
This module discusses the role of wind shear in the structure and evolution of convective storms. Using the concept of horizontal vorticity, the module demonstrates how shear enhances uplift, leading to longer-lived supercell and multicell storms. The module also explores the role of shear in the development of mesoscale convective systems, including bow echoes and squall lines. Most of the material in this module previously appeared in the COMET modules developed with Dr. Morris Weisman. This version includes a concise summary for quick reference and a final exam to test your knowledge. The m ...
