2. Winds always blow from ______to ______pressure. Use the arrow below as a starting point to answer/complete questions 3 – 6a.

Wind direction

3. Draw an “ H” where the high pressure is located and an “ L” where the low pressure is located. 4. Draw arrows to show where the air is rising and where it is sinking. 5. Label the cooler area and the warmer area 6. Draw a sun in the sunny area and a cloud in the area that is more likely to have precipitation. a. Why is this area more likely to have precipitation? ______7. Are we having high or low pressure today? How do you know? ______8. On the letters below, show how the air would be moving around the high pressure area and how they would be moving around the low pressure area. This is a “bird’s eye” view.

H L 9. Low pressure areas are zones of convergence/divergence , move clockwise/counterclockwise , and are cyclones/anticyclones . 10.If a cloud or fog has formed, then the air temperature at that spot has reached the dew point and has ______relative humidity.
