Why Does Weather Move From The West To The East?

Weather systems move from west to east because water currents and wind currents move from west to east. But why do they do this?

Wind is caused when air is heated up by the sun, and then, as a result of being warmer, this hot air rises. So cooler air then rushes in to take the place of the air that has moved upwards.

The air at the equator gets hottest, because it is nearer to the sun, so the rising air at the equator is replaced by air coming in from the north and the south. So we end up with a situation where the lower altitude winds are going towards the equator, and the higher altitude winds moving away from it.

Now we have to think about the rotation of the earth. The speed is faster at the equator than at the poles, so the high altitude winds, that have just left the equator, tend to drift east, keeping the same speed of rotation as at the equator.

So, for this reason, you have high altitude winds drifting east, and they carry the weather with them, causing weather systems to drift east.

It is due to the convection currents and also the Coriolis effect. The weather moving from west to east only happens at temperate countries, and in tropical climates, it moves from east to west, a complete change in direction. What cause this weather movement? It is due to the hot air in the equator rising up, and the cold air above sinking down to takes its place, and the weather moves north. The convection of air currents takes place and also the Coriolis effect also affect the weather pattern, that's why the change of weather direction.
