TERM 1 Atmospheric pressure DEFINITION 1 Atmospheric pressure is the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. Measured with a barometer TERM 2 Atmospheric pressure inceases: DEFINITION 2 with decreasing height, High pressure systems or decending air TERM 3 Atmospheric pressure decreases DEFINITION 3 with increasing height and low pressure systems or ascending air TERM 4 Isobar DEFINITION 4 A line connecting two areas of equal pressure at a give time TERM 5 Are the horizontal difference greater than the vertical differences DEFINITION 5 yes because because of the thermal(determinded by air temp) and dynamic aspect(reklated to atmospheric motion TERM 6 High pressure systems turn____ in the Northern hemisphere DEFINITION 6 CLockwise TERM 7 winds are named by DEFINITION 7 the direction the come from not going toward TERM 8 Pressure gradient DEFINITION 8 In atmospheric sciences (meteorology, climatology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes in which direction and at what rate the pressure changes the most rapidly around a particular location. A strong pressure gradient is shown by close iso bars TERM 9 why do pressure gradients develop DEFINITION 9 Air temp, topography, TERM 10 Coriolis effect DEFINITION 10 In physics, the Coriolis effect is an apparent deflection of moving objects when they are viewed from a rotating reference frame. TERM 21 warm ocean currents DEFINITION 21 warm water flows into areas of colder water TERM 22 How much water does the oceans and Glaciers hold DEFINITION 22 Oceans= 97.1 Glaciers= 2.24 TERM 23 HUmidity DEFINITION 23 Humidity is the amount of water vapor in the air. TERM 24 adiabatic process DEFINITION 24 In thermodynamics, an adiabatic process or an isocaloric process is a thermodynamic process in which no heat is transferred to or from the working fluid. TERM 25 tornado DEFINITION 25 A tornado is a violent, dangerous, rotating column of air which is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
