Wet bulb depression is 4°C Dewpoint is 10°C Dewpoint is -17°C Page 25 Wet bulb depression is 4°C Dewpoint is 10°C Dewpoint is -17°C Relative Humidity is 86% Warm air Rising air, expands & cools, then it reaches dewpoint and clouds will form (condensation) Weight if the atmosphere

Pressure differences due to the unequal heating of Earth’s surface Page 25 Pressure differences due to the unequal heating of Earth’s surface Isobars are very close together Winds blow from Hi to Lo pressure

Air is less or more dense Characteristic Low Pressure High Pressure Warm or Cold Air is less or more dense Air rising or sinking Clouds or no clouds Warmer Cooler Less dense More dense Sinking Rising Clouds No clouds Page 25

Isobars are very close together Winds blow from Hi to Lo pressure Page 25 WEST TO EAST Isobars are very close together Winds blow from Hi to Lo pressure

While drawing a front The Rule: triangles and bumps always point in the direction the front is moving Page 26

Cold Front- occurs when heavy cold air displaces lighter warm air, pushing it upward. Precipitation occurs ON the cold front 27. Page 26

Cold Fronts Class Zone Animation #1 Page 26

Warm Front- occurs when warm air replaces cold air by sliding over it. Precipitation occurs AHEAD of a warm front. 28. Front Page 26
