Valley Winds
1. Upslope Winds:
- Blow up sides of the valley during the DAY
- Valley sides heat up quicker
2. Valley/ anabatic winds:
- Blow during the DAY, from bottom to top of the mountain
- Valley floor is heated
- Top of mountain is narrower, so air is more constricted, heats up more ---> lower pressure
3. Downslope winds:
- Blow down the sides of the valley during NIGHT
- Air on high ground, at sides of valley, cools due to terrestrial radiation
Terrestrial radiation: heat given off by earth
4. Mountain/katabatic winds:
- Blows at NIGHT, from top to bottom of mountain
- Smaller air mass in upper part of valley cools down
- Becomes dense, heavy, and drains down valley to form wind
