In the Northern hemisphere, tropical air masses travel north from the equator to meet polar air masses, what do you think will happen if the two opposing air temperatures meet? What will be formed?
As air tries to move from high to low pressure in the atmosphere, the Coriolis force diverts the air so that it follows the pressure contours. In the Northern Hemisphere, this means that air is blown around low pressure in an anticlockwise direction and around high pressure in a clockwise direction.
