Forecaster Performance Criterion 3.1e

Forecasting hazardous phenomena affecting aerodromes

Performance Criterion Description:

The forecaster must prepare effective and timely forecasts for hazardous phenomena affecting aerodromes. These may include strong winds, cross-winds, squalls, frost, freezing precipitation, snow, lightning and wake vortices.

Scenario:       

During an assessment period the forecaster is confronted with meteorological conditions that could lead to hazardous phenomena affecting an aerodrome within the area of responsibility. The forecaster must respond appropriately.    

Evidence:

The forecaster applies appropriate forecasting techniques utilizing

• conceptual models
• interpretation of remote sensed data
• numerical and statistical output
• climatology
• terrain impacts
• airport operations

in order to predict

• critical winds
• frost
• hazardous precipitation
• lightning
• wake vortices 
• other phenomena
