Document Summary
Weather map: each one represents a diff system, trianlges cold front colour is typically blue, point the direction, semi-circles warm front. Isobars lines of equal pressure: how quickly/slowly pressure changes temp, close isobars rapid change in pressure over distance, farther isobars slower change in pressure over distance, 4mb (hpa) increments (996, 1004, 1008,) Weather and wind turn into: winds will turn counter-clockwise outside the system in a high pressure area, every 4 millibars (mb, use shorthand when recording pressure. Wind speed deduce how fast the wind is blowing. Cloud cover recorded in tenths: not included in some stations. Every weather station has these codes and they use those to look at the weather. If the temp of a gas is held constant and its volume is increased, then the pressure it exerts will decrease: volume and pressure of a gas are inversely proportional.
