Question
Draw isobars (lines of constant atmospheric pressure) with a contour interval of 4 mb on the weather map starting with 1000 mb. (a) Locate and identify the low pressure center (L). (b) Locate and identify the two fronts on the map by looking for changes in air temperature, wind direction, dew-point temperature, and cloud cover. Use appropriate symbolism when you draw the frontal boundaries.
1. Which states are currently receiving rain? How do you know?
2.Considering factors such as temperature, dew-point, cloud cover, wind speed, and wind direction, discuss the current weather in Little Rock, Arkansas, and Roanoke, Virginia.
3.Assuming that the midlatitude cyclone moves toward the east at 5oo miles/day, what is the weather going to be like in Little Rock, Arkansas, and Roanoke, Virginia, tomorrow? Be sure to include in relative terms how the temperature, humidity, cloud cover, and wind peed and direction will change (e.g. will it be warmer or colder than it is now?).
