TAFs use the same weather code found in METAR weather reports. Each country is allowed to make modifications or exceptions to the code for use in each particular country. TEMPS temperatures Terminal Aerodrome Forecast This NWS aviation product is a concise statement of the expected meteorological conditions at an airport during a specified period (usually 24 hours). Windy or cloudy conditions will tend to produce slow temperature recovery, while clear, calm weather can cause rapid recovery. Generally, the period between late evening and sunrise. Temperature Recovery The change in temperature over a given period of time. When the layer's base is at the surface, the layer is called a surface-based temperature inversion when the base of the layer is above the surface, the layer is called an elevated temperature inversion. Temperature Inversion (surface-based or elevated) : a layer of the atmosphere in which air temperature increases with height. This is the most measured quantity in the atmosphere. TEMP)- The temperature is a measure of the internal energy that a substance contains.
TEMP Temperature- A measure of the internal energy that a substance contains. HWRF: NWS/Hurricane Weather Research and Forecasting Model TCU Towering cumulus clouds TD Tropical Depression TDA Today TDWR Terminal Doppler Weather Radar Teleconnection Linkage between changes in atmospheric circulation occurring in widely separated parts of the globe. TCON Average of GHMI, EGRI, NGPI, HWFI, and GFSI Target Precipitation or other phenomena which produces echoes on a radar display. Tailwater Height In hydrologic terms, height of water immediately downstream of the dam.
Since low-level southerly inflow of warm, moist air into this storm is relatively unimpeded, such a storm often has a higher probability of strengthening to severe levels than the other storms in the line. Tail-End Charlie Slang for the thunderstorm at the southernmost end of a squall line or other line or band of thunderstorms. Compare with beaver tail, which is a form of inflow band that normally attaches to the storm's main updraft (not to the wall cloud) and has a base at about the same level as the updraft base (not the wall cloud). Cloud motion in the tail cloud is away from the precipitation and toward the wall cloud, with rapid upward motion often observed near the junction of the tail and wall clouds. The base of the tail cloud is about the same as that of the wall cloud. TAF Terminal Aerodrome Forecast TAFB Tropical Analysis and Forecast Branch (of the TPC) Tail Cloud A horizontal, tail-shaped cloud (not a funnel cloud) at low levels extending from the precipitation cascade region of a supercell toward the wall cloud (i.e., it usually is observed extending from the wall cloud toward the north or northeast). Since they are aligned parallel to the low-level inflow, they may point toward the region most likely for later storm development. Transverse rolls are one type of transverse band, and often indicate an environment favorable for the subsequent development of supercells. T Rolls Transverse Rolls - elongated low-level clouds, arranged in parallel bands and aligned parallel to the low-level winds but perpendicular to the mid-level flow. T Thunderstorm T -Number A system used to subjectively estimate tropical cyclone intensity based solely on visible and infrared satellite images. Press enter or select the go button to submit request
