Hurricane IRMA is a tropical hurricane

Vertical Structure of the atmosphere:
1. Trophosphere
a) Responsible for all weathers
b) Temperature decrease with altitude
c) Tropopause= no change in temperature with altitude (straight line)
2. Stratosphere
a) Temperature increase with height
b) Lots of ozone molecules
c) Stratopause= no change in temperature with altitude (straight line)
3. Mesosphere
a) Temperature decrease with height
b) Mesopause= no change in temperature with altitude (straight line)
4. Thermosphere
a) Close to energy source
b) Increase with height
Clouds can be classified by their nomenclature (system that is used to name something)

Document Summary
Know about the hurricane irma for the exam! Look at slides 21-27 in lecture 1-2 for clear images of different types of clouds. The attached image has clear explanation of the pressure gradient and its function on the movement of air. In slide 30, the two parallel lines are known as isobars. At any given points on the lines have the same pressure values. It is the prime cause for win the atmosphere. In this image there are two isobars that are not evenly spaced. The closely spaced isobars have greater pressure gradient force. When you are between buildings, you feel the strong air because the air is constricted. Whereas, when you are walking at the streets, there is no air being constricted. The image shown above is a good representation of the movement of wind. Wind does not move in the straight line, it will move in a wavy formation.
