I'm not an expert, but this is what I think is going on - from another weather thread.

Also the difference between the hot and the cold, and high pressure and low pressure, brings stronger winds (as in OK), or different winds when compaired with what we are used to. Also bigger pressure systems drag warm or cold air from further away than normal (more cold, or more hot) creating more extreme conditions on land.
