Weather Terms

Coastal Upwelling- this is defined as the moving of water from the deeper oceans upwards to the surface of the ocean very commonly found along our cold ocean currents, which are found along the West Coast of the United States and off the Peru coast.

Coastal Sinking- this is defined as the warm waters moving in from the east and hitting the coastline and slowly filtering down towards the deeper ocean waters very slowly. This feature is common in our warm ocean currents such as the United States East Coast and the currents off the east coast of Japan.

Sub-tropical High pressure- these are semi-permanent features that rotate clockwise and they can be found in the Northern Hemisphere and Southern Hemisphere. The two in the Northern Hemisphere are the Bermuda-Azores High and also the Pacific High, one in each ocean basin.

Easterly Waves- these are tropical features that are found in the Tropics of the Pacific and Atlantic Ocean. The importance of these waves is that they can contain a large area of t-storms and strong winds. If further development happens these waves will become tropical storms or hurricanes/typhoons. The reason they are named easterly waves is because they move from East to West in the Northern Hemisphere.
