Study Notes
Prognostic Charts vs Extended Surface Prognostic Charts
Scope and Detail
- Prognostic charts provide a general overview of expected weather conditions over a specific area for 48-72 hours in advance.
- They include information on pressure systems, fronts, precipitation, and temperature patterns.
- Extended Surface Prognostic charts offer more detailed information, covering larger geographical areas and providing forecasts for specific surface weather parameters.
- Parameters included in Extended Surface Prognostic charts are wind speed and direction, temperature, humidity, and precipitation.
Spatial and Temporal Coverage
- Prognostic charts focus on a particular region or area of interest, such as a continent, ocean basin, or specific country.
- They provide a snapshot of expected weather conditions at a specific time or for a short time period.
- Extended Surface Prognostic charts cover a broader spatial range, encompassing multiple regions or global-scale weather patterns.
- They provide forecasts for longer time periods, extending beyond 72 hours, for medium-range or extended-range weather prediction.
