Winds
Do want to fly a kite.You might need some wind
Local Winds
Definition- A local wind is a small region wind that is influenced by geographical features
created by unequal heating of earth surfaces
Sea breezes and Land breezes
Land breezes- blow from the land over to the ocean like a convection current.They are caused by the unequal heating of the land and then the low air pressure lifts the hot air over the land into the ocean.
Sea breezes-At night it is just the opposite it is the unequal heating of the ocean and then the high pressure lifts up the warm air over to the beach or the shore
Global winds
Global winds are wide spread winds that are caused by pressure belts and the Coriolis effect.Now a pressure belt is at the poles the cold air sinks and moves towards the equator but just the opposite in the south around 60 degrees the warm air starts to rise towards the equator causing a giant convection current.
Doldrums
The doldrums are located along the equator where no wind blows do to the warm air from the south moving up do to this creating an area of low pressure.
Trade winds,Prevailing easterlies and Jet streams
Trade winds-The trade winds are just air movements toward the equator. They are warm, steady breezes that blow almost continuously. The Coriolis Effect makes the trade winds appear to be curving to the west, whether they are traveling to the equator from the south or north.
Prevailing Easterlies-At about sixty degrees latitude in both hemispheres, the prevailing westerlies join with the polar easterlies to reduce upward motion. The polar easterlies form when the atmosphere over the poles cools. this cold air then sinks and flows over the earths surface
Jet streams-A jet stream is a fast moving pocket of air found about 12 km above the earths surface.They form boundaries of different heat masses so on one side the air is warmer but on the other side the air can be really cool.
Definition of wind
Wind is air in motion. It is produced by the uneven heating of the earth’s surface by the sun. Since the earth’s surface is made of various land and water it form the unequal heating of the earths surface
What causes wind
Some of the earths surfaces do not get direct rays there for they are unequal heating of the ground.Warm air rises but then the cold air falls causing convection currents.
