Question 1
"Perhaps more than any other single measurement, atmospheric pressure is the best indicator of current and changing weather conditions." Briefly discuss why this statement is correct.Question 2
On the weather map below, describe the wind pattern and the relationship between the winds and isobars.

Answer 1
Pressure change is easy to understand and recognize patterns. When air pressure increases the weather typically improves and when it decreases it becomes more cloudy and stormy.Answer 2
The winds are blowing away from the high pressure center and toward the low pressure center. Winds are strongest near the center of the low, where the isobars are most closely spaced. The winds are all deflected with respect to the isobars due to near surface friction between the moving air and the ground surface, otherwise the winds would be parallel to the isobars due to Coriolis forces.Post by: Denise Boudreau on Dec 12, 2021
