Also why is there strong wind in some area?

No. the wind is caused by the heating and cooling of the earth along with some help from high and low pressure systems.

No, the earth's rotation has no affect on the time that it takes you to fly from one destination to the next. The speed of earth's relative rotation speed underneath a hovering object is 0, so it doesn't matter which direction you go when you consider earth's rotation, it's the winds that influence this. The reason why a hovering craft will not move as the earth rotates is due to the fact that the helicopter is already moving at 1,000 miles/hour with the earth. Imagine running or riding in a car at a constant rate and you through a ball up in the air. It moves with you. If you through the ball inside the car it will traverse the same distance in different directions in the same amount of time. If the earth did rotate beneath the earth then north or southbound flights would have to compensate, which they don't, they only compensate for the curvature of the earth because a straight line is not the shortest distance on a curved surface. If it was an hour and a half air time which is about the distance from Tampa, FL to Pittsburgh, PA and the earth rotated beneath the plane at 1,000 miles/hour then the plane would be offset by about 23 degrees longitude to the west given the fact that every hour about 15 degrees of longitude are covered by the earth's rotation.

That is part of the reason. When an object is spinning, there is something that occurs called the "Coriolis effect". For example, if you and a friend were on a merrygo round at opposite ends, and you tried to throw a ball to your friend, you would miss, and it would look like the ball curved away! Of course this didn't really happen, but it only looks like that because you and your friend are spinning. The wind is caused by many factors, but the coriolis effect caused by the spinning of the earth does contribute to things such as the large windstorms, like hurricanes.

Earth's rotation determines the general direction of prevailing winds and rotation direction of them, but wind is caused by a number of factors: regional pressure differentials, temperature differences etc.

it is hard to answer your question , generally speaking , the wind is caused by the temperature , (because warm air tends to rise up ), (cold air is heavier than warm air )
e.x in one hot area. the air will rise up ,and as more and more air rise up , this will cause an high pressure in this place relative to its surrounding . when the pressure is engouh big, the warm air will move to its surrounding area because there is a low pressure .
but earth rotation also plays a role , because when earth rotates ,the side facing to the sun will absorb energy causing temeprature rise . and the earth `s rotation can also affects wind `s direction .

Winds are caused by temperature differences in the atmosphere.

In a way of speaking. What I have heard is that the tidal movements of our oceans, governed by the magnetic pull/pressure of the moon create what we call wind.

The sun / heat differential is the driving force behind weather...
