Global Patterns
Weather can be influenced by different forces, such as global patterns. To know how global patterns effect weather you must first know what global patterns effect it.
Two jet streams effect our weather in the U.S, and they are the polar and the subtropical jet. They move the weather to us that effects us. The polar jet creates a boundary between cold North Pole air and warmer air from the equator. The polar jet moves south and becomes stronger in the winter. Places not by jet streams tend to have one kind of weather for a long amount of time. Because they move around air masses and some weather they can also cause changes in temperature and air pressure.
Ocean currents effect the humidity, and the wind speed and direction. Currents are generated by things like the Earth's rotation, wind, temperature, and the moon's gravity. When the ocean water evaporates, it can make air more humid and effect the temperature of the air. This helps effect precipitation by creating storms that are later carried off by the wind.
- Jet Streams: Narrow, fast flowing air currents that circle the globe. They are located several miles above the Earth. Jet streams usually run from west to east.
- Ocean Currents: Permanent continuous directed movements of ocean water located throughout Earth's ocean.
