Pressure does not increase in a regular pattern from the equator to the poles There are regions of high pressure and low pressure in the subpolar regions and subtropics This is related to atmospheric circulation Air rises at the equator and encounters the tropopause and splits into two air currents flowing in opposite directions (north and south). Air piles up aloft from middle latitudes and will descent, producing high pressure in the subtropical regions. Collision of air @ 60 degrees causes air to rise. Wind is the movement of air in response to differences in atmospheric pressure. Winds are named for where they come from Wind from NE is called NE wind Prevailing winds

Unformatted text preview: How might vegetation differ on the windward and leeward sides of an island? Coriolis Effect On global scales, the direction of the wind is more complicated simply due to the Earth’s rotation, via Coriolis Effect. Developed by French scientist: Gaspard-Gustave de Coriolis - 1835 Coriolis Effect: effect of the Earth’s rotation that acts like a force to deflect a moving object on the Earth’s surface. Anything (air, water, airplane, etc) moving horizontally appears to be deflected: To the right in the northern hemisphere To the left in the southern hemisphere • Acts at right angles to direction of motion • No deflection at equator, maximum deflection at poles...
