leave wind out of the story does weather follow with earths rotation if not we move towards new weather

As the earth rotates on its axis, the atmosphere is rotating with it. Otherwise there'd be a constant wind, like in a fast-moving car on a still day, as we were dragged through the atmosphere at the speed of the earth's rotation, yes? And all winds would blow from east to west, and we know that's not the case.

But the rotation of the earth does have an important effect on the weather. A strange thing about rotating a globe is that a point on the equator has to move much faster to make it all the way around the waist of the globe in 24 hours than a point up around the Arctic circle has to move to make it all the way around the Arctic circle in 24 hours. (you can test this with a piece of string: The length of a piece of string wrapped around a globe at the level of New York is much shorter than a piece of string wrapped around the globe at the equator, right?)

You know that, looking at the globe with the sun behind your back, as the world turns, the continents pass off to the right (the east). New York crosses into the sun at dawn while San Francisco is still on the dark side of the globe. Because the surface of the earth at the equator is rotating faster than the surface of the earth 500 miles north of the equator, so is the air above it. But the air above the equator isn't attached to the air above a point 500 miles north. So the faster-moving and slower-moving air rub past each other. This forms a kind of bow wave at the equator, like the wave that peels back from the bow of a boat as it moves through the water. Think of a big arrow pointing to the right and wrapped around the equator. So the air peels back to either side of the equator, and forms a swirling current--curling counter-clockwise above the equator and clockwise below it. This is called the coriolis wind. It's one important factor in where weather comes from.

Climate is the long term conditions of a place over the years. Weather is the short term conditions over the days.
Climate depends on the way an area responds to the combination of latitude, altitude, and geography.
Weather depends on the current weather systems around the globe which are the result of sea water temperature and jet streams.
The formula is very complicated and includes an 11 year Solar cycle, and a 20 year ocean temperature cycle. Other cycles such as El Niño are not as regular. The jet stream is almost unpredictable.
Over a long time these average out to what we call climate, but since we don't know exactly what will happen 10 days later, we call it weather.
Carry an umbrella to match your climate and you will be right most of the time. If it is important day, listen to the weather report.

Without any wind, the clouds move with us...
