Product Description
Abstract: These polyline shapefiles identify worldwide forecasts of jet steam axis locations at 6, 12, 18 and 24 hours into the future based on analyses of upper level wind products by DTN meteorologists. Jet stream forecast shapefiles are updated every 6 hours.
Purpose: These shapefiles can be used to plan flight routes and manage aircraft around headwind threats and to optimize aircraft fuel usage.
Description: These worldwide polyline shapefiles identify forecast location and maximum speed of jet steam axis at 6, 12, 18 and 24 hours into the future based on analyses of upper level wind products produced by DTN meteorologists. This layer is typically used to build a high level significant aviation weather forecast product. Jet stream forecasts are updated four times a day.
