1. Types of Fronts  Now that we have learned the concepts of density, we can better understand what fronts are and how they affect the weather. 1)Cold Front: A transition zone where cold/dry, and stable air, replaces warm/moist, and unstable air. It is depicted by a blue line with triangles pointing towards the direction of movement.

2. Cold Front Warmer Temperatures Colder Temperatures 27 33 62 54

3. Cold Front (Vertical Profile) Rising Warm air Advancing Cold air

4. Warm Front 55 62 Warm Front Warmer Temperatures Colder Temperatures 45 38

5. Warm Front (Vertical Profile) Cold air Warm air

6. Stationary Front Warm Air Cold Air

7. Mapping Exercise  Draw and analyze a surface weather map for pressure and temperature, and draw the fronts that are indicated by these two variables.

13. Wind direction The wind barb (parts ff and dd combined) is like an arrow and points in the direction the wind is blowing. The suffix -erly means the wind is blowing from that direction. Here are a few examples of how to describe wind direction:

14. Sky Cover The total amount of clouds in tenths.

16. Which direction is the wind blowing and at what speed?
