Storms can be very localized, and the rain and hail associated with them can be similarly localized. There are complex factors that affect a storm and often times, they differ vastly from the 60,000 foot crown of the storm, all the way down to where it impacts the surface. Wind shears, temperature changes and a long list of other components of a storm are constantly reacting to each other and changing. The final result of a storm is difficult to understand and almost impossible to predict.
Long-lived thunderstorms have a typical structure which is created when warm and humid air rises and condenses as it cools, causing rain. As this rain falls, it may evaporate and lead to cooling behind the storm, creating storm outflow. This outflow spreads out as it hits the ground and helps lift the warm humid air feeding the storm. Often, an observer in the path of the storm will first feel the warm humid air well ahead of the storm, and then the cool wedge of air from the storm outflow before finally experiencing the rain associated with the storm itself.
Temperature inversions form in the atmosphere whenever the air temperature increases with . They can form in the summer in valleys or even shallow depressions as cool air flows downward and accumulates in the low spots. They may also form in the winter after a storm as the very strong cooling of a snow covered surface at night causes relatively cold temperatures near the surface. Inversions act as a lid on upward motion, creating stable and static conditions while they exist.
A hurricane is a low pressure system of tropical origin containing organized thunderstorm activity that produces sustained winds of at least 74 mph. Guess what? A typhoon is the same thing! Let me repeat; a hurricane and a typhoon are the same. From a meteorology perspective, there is absolutely NO DIFFERENCE between a typhoon and a hurricane (and for that matter there is no difference among a hurricane, typhoon, tropical cyclone or severe cyclonic storm). So why the different names? It all has to do with what ocean basin the storm resides in. Hurricanes are known by different names in various regions of the world.
Hurricanes are in the Atlantic ocean or eastern Pacific Ocean. A typhoon is the same type of storm only in the western Pacific.
