Hurricane Large storm formed over warm water & must have winds blowing at at least 64 knots. Counterclockwise Direction that a hurricane spins in the northern hemisphere. Nor'easter Winter storm that brings high winds & precipitation. Sea Breeze Local wind that comes from the sea, during the day. Land Breeze Local wind that blows from land to the ocean during the night. Local Wind A wind that only affects a small area. Monsoon A season-long local wind which results in a rainy season & a dry season. Winter Monsoon A large-scale local wind that is the equivalent of a land breeze. Summer Monsoon A large-scale local wind that is the equivalent of a sea breeze. Equator Place on earth that receives the most sunlight. 23.5 degrees The latitude at which the two tropics are at. Corresponds also to the tilt of the earth's axis. Heat Budget The balancing of heat entering the atmosphere to heat escaping the atmosphere Air Pressure The vertical movement of air in a convection current. Wind The horizontal movement of air in a convection current. Coriolis Effect Caused by the rotation of the earth, this seems to deflect objects moving above the earth's surface to the left or right. Clockwise (or to the right) Direction that objects seem to be deflected towards in the northern hemisphere. Counterclockwise (or to the left) Direction that objects seem to be deflected towards in the southern hemisphere. Doldrums Area of low pressure & lack of winds at the equator. Horse Latitudes Area of high pressure & lack of winds at 30 degrees latitude. Tradewinds Global winds that come from the Northeast or Southeast. Westerlies Global winds that are located between 30 degrees & 60 degrees latitude. Polar Easterlies Global winds that would be found near the poles. Subpolar Low Low pressure located at 60 degrees latitude. High Pressure Sinking air located at 30 degrees latitude and the poles. Low Pressure Rising air located the equator & at 60 degrees latitude.
