LACEMOPS Factors That Affect Climate llhammon Strategy

“L” (latitude)

“A” (air masses) An air mass is a large (usually thousands of miles across) volume of air that has horizontally uniform properties in terms of temperature, and to a lesser extent humidity

“C” (continentality) A measure of how the climate of a place is affected by its remoteness from the oceans and oceanic air. The difference between the average temperatures prevailing in January and July is most often quoted as an indicator of this.

“E” (elevation) At higher altitudes, temperatures grow colder by approximately 4 degrees Fahrenheit for every 1,000 feet. This cooling effect stems from low atmospheric pressure -- with less air to push down on the mountains, the air molecules spread out and lose energy.

“M” (mountain barriers) The air that descends from the mountain warms up and vapor pressure increase which results the relatively humid to lower and air becomes drier. thus, mountain barrier can affect precipitation/winds and these factors affect the climate.

“O” (ocean currents) An ocean current is a continuous, directed movement of ocean water generated by the forces acting upon this mean flow, such as breaking waves, wind, Coriolis effect, cabbeling, temperature and salinity differences and tides caused by the gravitational pull of the Moon and the Sun

“P” (pressure and wind belts) A pressure belt is an area which has consistently high or low pressure. Winds move from areas of high pressure to areas of low pressure. The belts tend to move with the seasons, toward the equator in winter and toward the poles in summer.

“S” (storms) A storm is any disturbed state of an astronomical body's atmosphere, especially affecting its surface, and strongly implying severe weather.
