1. Winds occur because the earth is heated unequally. Warmer areas have low pressure and cooler areas have high pressure. Winds occur because air will always move from areas of high pressure (more dense)to low pressure (less dense).
2. We measure wind speed with an anemometer. We measure the direction the wind is coming from with an anemometer.
3. Local winds blow over short distances. Global winds blow over long distances.
4. Sea and land breeze occur due to unequal heating of the water and the land.
During the day, the land heats faster than the water. So, the high pressure cool air over the water blows to the land (low pressure) as a sea breeze.
At night, the land cools faster than the water. So, the high pressure cool air over he land blows to the water (low pressure) as a land breeze.
5. Global winds occur because the whole earth is not heated equally by the sun so pressure differences develop. Global winds curve due to the fact that the earth is rotation--this is called the Coriolis effect.
