Typhoon Help
Typhoons : Formation, temperatures, latitudes, movement, speed, can they cross the equator, what will happen to your performance in a typhoon, what happens to Mach number in a typhoon.
Typhoon, Hurricane, cyclone
ifferent names for the same thing?

Answered some of my question myself
The terms "hurricane" and "typhoon" are regionally specific names for a strong "tropical cyclone". A tropical cyclone is the generic term for a non-frontal synoptic scale low-pressure system over tropical or sub-tropical waters with organized convection (i.e. thunderstorm activity) and definite cyclonic surface wind circulation (Holland 1993).
Tropical cyclones with maximum sustained surface winds of less than 17 m/s (34 kt, 39 mph) are called "tropical depressions" (This is not to be confused with the condition mid-latitude people get during a long, cold and grey winter wishing they could be closer to the equator ;-)). Once the tropical cyclone reaches winds of at least 17 m/s (34 kt, 39 mph) they are typically called a "tropical storm" and assigned a name. If winds reach 33 m/s (64 kt, 74 mph)), then they are called:
· "hurricane" (the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, or the South Pacific Ocean east of 160E)
· "typhoon" (the Northwest Pacific Ocean west of the dateline)
· "severe tropical cyclone" (the Southwest Pacific Ocean west of 160E or Southeast Indian Ocean east of 90E)
· "severe cyclonic storm" (the North Indian Ocean)
"tropical cyclone" (the Southwest Indian Ocean)

I am assuming you are getting ready for a cx interview.
-water surface temp at least 26.5 degrees celsius.
-between 5-15 degress latitude
-can cross the equator but will weaken very quickly upon crossing.
-temp. in the cyclone can be isa +25 or higher so performance degradation based on warmer temp.
-a google search, prune search or use of the AWARE wx manual on TC website should get you the rest of the info to fill in the blanks.
hope this helps and good luck.
