A cooler breeze from a large body of water.

An instrument for measuring the wind speeds.

An instrument measuring atmospheric pressure, used especially in forecasting the weather.

Relatively narrow bands of strong wind (up to 275 mph) in the upper levels of the atmosphere. They flow high overhead and cause changes in the wind and pressure at that level. They cause changes that can make extreme weather events worse.

One of the first steps that was taken to estimate wind speeds and the effects. The chart starts with 0 and goes to a force of 12. The chart is still used today to estimate wind strengths.

These blow in a certain direction and speed over a specific geographic region or at certain times of the year.
