Warmer air rises, while cooler air drops. Winds are defined as moving air that travels around the earth. If all areas on earth had the same pressure and temperature there would be no wind. Winds are driven by solar energy.

Diagram 1: Cool air travels towards the land while the warm air heats the up the atmosphere.
Diagram 2: Cool air is traveling towards the ocean from the land. While the warm air is traveling towards the atmosphere.
Both diagrams show sea breezes. Cooler air is more dense and will sink over the land, but it will also push the less dense, hot air above it, to the sky. During the day, there are land breezes; during the night, there are sea breezes. Land warms up and cools down quicker, while water takes a longer time. So in the day, the land will heat up faster, while the water will still be cooler. On the other hand, in the night, the land will cool down very fast, but the land will be warmer because it will take time to cool down.

A jet-stream is a fast-moving current of air located in the upper part of the troposphere. They usually move west to east due to the Earth's Rotation. Most weather systems go west to east because they are propelled by these jet streams. In winter, the polar jet stream lets the cold Canadian air go all the way to Texas. There are also tropical jet steams, but these don't influence weather like jet streams do. jet streams form at the boundaries of air masses with different temperatures. These are global winds and stay all year long. Global winds are caused by convection in the sky and uneven heating from our Sun. They blow high in the sky, but not near the ground.

Air pressure is the weight of air pressing against us. Air pressure changes as the density of air changes. Air takes up less space when it contracts or it's cooled. Its density also decreases. Matter with greater density sinks in a fluid, such as air, more easily. When cooler air sinks, it puts more pressure on the land below it. Sinking air creates an area of big pressure on the Earth's land. The air moves from the high pressured air to the low pressured air, generating air.

Air pressure changes as the density of air changes. Cooler air contracts, and becomes more dense. This creates high pressure. Air masses are large sections of the troposphere. These move and travel, causing a lot of the weather we get. Isobars are lines on the
weather map that show us which places have the same air pressure. These predict wind speeds and places of high and low air pressure. This cool air causes clear and dry weather. Warm air usually causes humid air, clouds, and rain. This additionally causes our natural disasters like tornadoes and thunderstorms. The movement of the air masses change the weather.
