Best TrackA subjectively-smoothed representation of a tropical cyclone's location and intensity
over its lifetime. The best track contains the cyclone's latitude, longitude, maximum
sustained surface winds, and minimum sea-level pressure at 6-hourly intervals.
Best track positions and intensities, which are based on a post-storm assessment
of all available data, may differ from values contained in storm advisories. They also
generally will not reflect the erratic motion implied by connecting individual center fix
positions.Congestus(or Cumulus Congestus) - same as towering cumulus. CrestHighest point in a wave.
In hydrologic terms, (1) The highest stage or level of a flood wave as it passes a point. (2) The top of a dam, dike, spillway, or weir, to which water must rise before passing over the structure. Crest GageA gage used to obtain a record of flood crests at sites where recording gages are installed.Crest WidthIn hydrologic terms, the thickness or width of a dam at the level of the crest (top) of the dam. The term "thickness" is used for gravity and arch dams and "width" for other types of dams.Cumulus CongestusA large, towering cumulus cloud with great vertical development, usually with a cauliflower-like appearance, but lacking the characteristic anvil of a cumulonimbus.Domestic ConsumptionIn hydrologic terms, the quantity, or quantity per capita, of water consumed in a municipality or district for domestic uses or purposes during a given
period, generally one day. It is usually taken to include all uses included within the term Municipal Use of Water and quantity
wasted, lost, or otherwise unaccounted for.Domestic Use of waterIn hydrologic terms, the use of water primarily for household purposes, the watering of livestock, the irrigation of gardens, lawns, shrubbery, etc.,
surrounding a house or domicile.Effective Terrestrial RadiationThe difference between upwelling infrared or terrestrial radiation emitted from the earth and the downwelling infrared radiation from the atmosphere ESTEastern Standard TimeEstuaryIn hydrologic terms, the thin zone along a coastline where freshwater systems and rivers meet and mix with a salty ocean (such as a bay, mouth of a
river, salt marsh, lagoon).Esturine watersIn hydrologic terms, deepwater tidal habitats and tidal wetlands that are usually enclosed by land but have access to the ocean and are at least
occasionally diluted by freshwater runoff from the land (such as bays, mouths of rivers, salt marshes, lagoons). Esturine ZoneIn hydrologic terms, the area near the coastline that consists of esturaries and coastal saltwater wetlandsExtraterrestrial RadiationThe theoretically-calculated radiation flux from the sun at the top of the atmosphere, before losses by atmospheric absorption.Flood CrestMaximum height of a flood wave as it passes a certain location.Forecast CrestIn hydrologic terms, the highest elevation of river level, or stage, expected during a specified storm event.Height Above the Nearest Drainage (HAND)A relative elevation methodology used in inundation mapping, which determines the height of every point on a land surface above the nearest stream reach to which it drains.Prevailing WesterliesThe westerly winds that dominant in middle latitudes.Quantitative Precipitation Estimate (QPE)A spatial and temporal analysis estimating the amount of precipitation that has occurred using a variety of techniques including observational and remote sensing data.Rain ForestA forest which grows in a region of heavy annual precipitation. There are two major types, tropical and temperate.Rainfall EstimatesA series of NEXRAD products that employ a Z-R relationship to produce accumulations of surface rainfall from observed reflectivity.Spillway CrestIn hydrologic terms, the elevation of the highest point of a spillway.Tropical Cyclone Position EstimateThe National Hurricane Center issues a position estimate between scheduled advisories whenever the storm center is within 200 nautical miles of U.S. land-based weather radar and if sufficient and regular radar reports are available to the hurricane center. As far as is possible, the position estimate is issued hourly near the beginning of the hour. The location of the eye or storm center is given in map coordinates and distance and direction from a well-known point. Wave CrestThe highest part of a waveWest African Disturbance LineA line of convection about 300 miles long, similar to a squall line. It forms over west Africa north of the equator and south of 15 degrees North latitude. It moves faster than an Easterly Wave between 20 and 40 mph. They move off the African coast every 4 to 5 days mainly in the summer. Some reach the American tropics and a few develop into tropical cyclones.West WallThe coast side boundary of the Gulf Stream, typically south of Cape Hatteras. See also North Wall WesterliesThe prevailing winds that blow from the west in the mid-latitudes.
