Lesson 7: Background: Winds
Wind vectors from satellite images are calculated in two fashions:
- tracking moisture gradients using water vapor images is used in clear and cloudy regions, this method is commonly applied to 6.7 micron water vapor images, and
- detecting a cloud and tracking its motion through a sequence of images, this method is commonly applied to IR-window and visible images.
Wind direction can also be inferred through analysis of cloud patterns.
- Determining atmospheric winds using a sequence of satellite observations
- Sea and lake breezes
- Blowing-snow
- Thunderstorm outflow boundaries
- Flow around mountains
- Cloud streets and lines
