HRD FAQ: Tropical Cyclones (Q and A)

C: Celcius (a commonly used temperature scale, used for describing sea-surface temperature or cloud-top temperature)
CAT: Category (a number between 1 and 5, this is the category on the Saffir-Simpson Scale assigned to a storm based on its maximum winds)
CDO: Central Dense Overcast (the high, cold shield of clouds over the center of a cyclone... caused by deep convection)
F: Fahrenheit (a commonly-used temperature scale, used for describing sea-surface temperature or cloud-top temperature)
IR: Infra-Red (a frequency commonly used in satellite data to help determine cloud-top temperatures... has poorer resolution than VIS, but can be used at all times of day)
ITCZ: Intertropical Convergence Zone (area of enhanced convection encircling the globe where the Northern and Southern Hemisphere tropical winds collide)
kts: knots (used to describe storm motion and wind speeds... 1 knot equals 1 nautical mile per hour, or 1.15 statute miles per hour)
mb: millibars (a unit of pressure... 1013mb is standard sea-level pressure)
mph: miles per hour (used to describe storm motion and wind speeds)
MPI: Maximum Potential Intensity (theoretically, the strongest winds or deepest pressure a hurricane can achieve given current environmental conditions)
MSLP: Minimum Sea-Level Pressure (the lowest pressure found at the cyclone's center... either by aircraft recon or by satellite estimation techniques)
MWS: Maximum Wind Speed (the highest winds found in the cyclone's eyewall, either by aircraft recon, buoys, or satellite estimation techniques)
NHC: National Hurricane Center (the governing US agency responsible for issuing forecasts, advisories, watches, and warnings for all Atlantic and East Pacific hurricanes)
RMW: Radius of Maximum Winds (distance from the center of circulation where the winds are the greatest... i.e., the eyewall radius)
SST: Sea-Surface Temperature (the skin temperature of the ocean... found using ships, buoys, and satellites)
TC: Tropical Cyclone (general term for any warm-core weather disturbance with cyclonic winds)
TD: Tropical Depression (a low-pressure system with closed circulation and MWS of less than 35 kts)
TS: Tropical Storm (an organized low-pressure system with maximum winds between 35-63 kts)
TUTT: Tropical Upper-Tropospheric Trough (a trough most notable at 200mb characterized by subsidence in the center and winds wrapping cyclonically around the trough)
VIS: Visible (a frequency used in satellite data to view storms during daylight hours... has higher resolution than IR, but only works during daylight hours)
Z: Zulu (this means Zulu time --or GMT or UTC--... it is placed after a time, like 12Z or 2315Z. During the summer months, EDT is 4 hours behind UTC, CDT is 5 hours behind UTC, etc.)

Hurricane Floyd, Sep 07-16, 1999.	Hurricane Floyd will go in the history books as one of the largest and most devastating hurricanes. Islands in the Bahamas were virtually leveled and more than a dozen US states suffered from overwhelming floods.
Hurricane Bret, Aug 18-23, 1999.	Hurricane Bret was one of the most powerful hurricanes to hit the Texas coast in decades. Visit this brief page and learn a little about his history and view some beautiful images of his Texas landfall.
