Why does weather move from the west to the east?

Answer 1

During a day the West takes a lot of sunshine (hot air) but the east cools down (since it is under darkness)

On the eastern side, however, air becomes cooler since around midnight sunshine has ended nearly 4, 5, or 6 hours ago. As a result, on the eastern side weather is cool. When sunlight hits (around 2 p.m.) hard, air becomes hotter and this air moves upward.

Air moves eastward because it transitions from a hot to a cool state.

Low pressure spins counterclockwise, causing weather systems to move from west to east in the Northern Hemisphere.

It is noteworthy that precipitation in the Northern Hemisphere typically flows from west to east. This is primarily because air pressure is lower further north (in North America, for example) than it is in the tropics. Low pressure systems rotate counterclockwise, which causes winds to move from the west to the east, which in turn propels weather systems eastward.

The Jet Steam, which is driven by a number of factors including the sun's heat, which primarily targets the equator, the speed of the Earth's spin, and others, travels from West to East across North America and is another MAJOR factor that drives weather systems in the United States.

Though this isn't always the case, weather systems can actually move in any direction. For example, tropical cyclones, which include hurricanes, tropical storms, and tropical depressions, frequently move from east to west because they form over warm sea waters and follow westward-moving trade winds (which is how hurricanes end up on the east coast of the United States). Eventually, tropical systems can recurve and move back eastward.

Note that weather movement from west to east occurs only in certain regions of the globe. It depends on where you are.

Prevailing weather patterns refer to the movement of entire air masses, not just the winds they produce in their rotations. One air mass can blow in warm dry air today and cold wet air in hours, or tomorrow.

Prevailing weather is the result of expansive convection currents formed by the temperature differences on the surface of the earth as latitude increases. The Coriolis effect adds the twist.

As air heats up due to the direct rays of the sun and higher temperature at the equator, it rises and moves up into the atmosphere where it cools again and begins to flow high aloft, at the same time turning north or south depending on its origin.

In both hemispheres the convection current meets a similar convection current generated in the temperate latitudes of earth, and both force each other back down towards the ground. Again the air splits and begins to return to its origin. It flows along the ground to complete the convection current circuits.

Near the earth's poles, the same event is also in progress, except the colder air produced there stays near the ground on its journey south or north, then rises as it is heated, where it meets the other side of the temperate air described above. The warmer air ascends to the top of the atmosphere where it again is re-directed back to its origin.

During all this activity spin of the earth results in the Coriolis effect which deflects the winds towards the right in the northern hemisphere and to the left in the south. Depending on which hemisphere and the latitude of a particular location, the effects of these two phenomenon will determine the prevailing weather.

Weather moves from west to east primarily due to the Earth's rotation and the distribution of landmasses and oceans across the globe, which influence the flow of atmospheric circulation known as the prevailing westerlies.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
