Latitude is 0 degrees to 30 degrees.
WESTERLIES occur at the mid-latitudes and carry WARM air from the SOUTHWEST to the NORTHEAST;
Latitude 30 degrees to 60 degrees
POLAR EASTERLIES occur at the north and south poles carries LOW COLD AIR from the NORTHEAST to the SOUTHWEST;
Latitude 60 degrees to 90 degrees

Weather Fronts
Occur when warm air replaces cold air. Rises creating smell clouds and light rain. Move much slower than cold fronts.
Warm Fronts
Occur when cold air replaces warm air. Move much faster than warm, causes the warm air to rise vertically. Heavy clouds and thunderstorms.
Cold Air
Occur when a cold front over takes a warm front.
Occluded Front
