DescriptionDLAC 1 is designed to give forecasters a comprehensive understanding of the physical mechanisms, synoptic patterns, and mesoscale features involved in fog/stratus generation and dissipation, as well as the latest forecast tools used to predict these challenging events.
Goals and ObjectivesCourse Objectives
- Develop an increased awareness of the various users of ceiling and visibility forecasts and how forecasts of these conditions impact aviation operations within each user group
- Explain the significant physical mechanisms that dominate the evolution of radiation and advection fog episodes
- Apply an understanding of the mechanisms involved in the development, maintenance, and dissipation of radiation and advection fog to successfully forecast these episodes using both observations and model data
- Recognize weather patterns associated with fog and stratus formation
- Know what forecast tools and products are useful for evaluating environmental factors associated with fog and low stratus
- Write a user-friendly TAF that conveys ceiling and visibility information
The Distance Learning Aviation Courses (DLAC) are a series of lessons, units, and cases designed to help aviation forecasters improve both their ability to forecast aviation hazards and to write terminal aerodrome forecasts (TAFs) that convey these hazards to aviation forecast customers.
The overall objectives for the DLAC courses are to:
- Develop an increased awareness of the various users of aviation forecasts and how forecasts of aviation hazards impact (both positively and negatively) aviation operations within each user group
- Explain the significant physical mechanisms and weather patterns responsible for aviation hazards
- Give forecasters an understanding of observations, forecast tools, and model data that can help improve the forecasting of aviation hazards
- Provide practice in writing a TAF that is user-friendly
Courses and Resources
Courses currently available are:
- DLAC 1: Forecasting Fog/Low Stratus for Aviation Operations: Provides a comprehensive understanding of the physical mechanisms, synoptic patterns, and mesoscale features involved in fog/stratus generation and dissipation, as well as the latest forecast tools used to predict these challenging events. Introduces the Practically Perfect TAF (PP TAF) method for conveying ceiling and visibility information in a TAF.
- DLAC 2: Producing Customer-Focused TAFs: Emphasizes understanding how aviation customers use TAFs, how weather hazards conveyed in TAFs affect their decisions, and what constitutes a "good" or "poor" TAF from the customer's viewpoint. Also reviews the PP TAF technique introduced in DLAC 1 and provides additional practice in writing PP TAFs for various weather conditions.
