48-hr Tropical Cyclone Formation Probability Product Product Description

NOTE: NESDIS maintains the official operational product, which can be found at www.ssd.noaa.gov/PS/TROP/TCFP/index.html.

NCEP global forecasts, Reynolds weekly sea surface temperature, and GOES-East, GOES-West, MTSAT-1R and Meteosat-7 channel-3 (water vapor) imagery are used as input to an algorithm to estimate the probability of tropical cyclone formation within 500km of each grid point within the next 48 hours 45 S to 45 N and 0 to 360 E. The product domain is divided into 7 main basins (below) based on satellite coverage and warning agency boundaries.

Figure: TCFP basins

INPUT PARAMETERS:

CLIM: Climatological TC formation probability. This was derived from the NHC Atlantic and east Pacific best track files from 1949-2010. Formation was defined as the first entry of tropical depression or higher in the best track. Extratropical cases were excluded.
PLND: The percent of the area covered by an r=500km circle covered by land
DNST: The closest distance to any existing tropical cyclone.
RSST: The average weekly Reynold’s SST.
VSHD: The average 850-200 hPa vertical shear.
RVOR: The average 850 hPa relative vorticity.
THDV: The average vertical instability parameter, defined as the vertical average temperature difference between the equivalent potential temperature of a parcel lifted from the surface to 200 hPa, and the saturation equivalent potential temperature of the environment.
HDIV: The average 850 hPa horizontal divergence.
PCCD: The percent of channel 3 pixels colder than -40 degree. All full disk images within 3 hours after and 6 hours before each synoptic time are include, so that this parameter represents the amount of sustained deep convection.
BTWM: The average channel 3 brightness temperature, after the cold pixels in parameter 9 above have been eliminated. This parameter is a measure of mid- to upper-level moisture.
MSLP: The average mean sea level pressure.
TADV: The average 850 hPa horizonal temperature advection.

**Note: all parameters except DNST computed over a 500km radius area centered on each grid point

CLIMATOLOGY:

Climatological input parameters are computed over the following time periods:

CLIM: 1949-2010
RSST,VSHD,RVOR,THDV,HDIV,MSLP,TADV: 1995-2010
BTWM,PCCD (N Atlantic): 1995-2010
BTWM,PCCD (NE/NCentral Pacific): 1998-2010
BTWM,PCCD (NW Pacific): 2000-2010
BTWM,PCCD (Indian Ocean, S Pacific): 2005-2010
BTWM,PCCD (S Atlantic): 2008-2010

ALGORITHM METHODOLOGY:

The formation probability is calculated by a three-step algorithm. First, all cases where input parameter values exceed predetermined thresholds are screened out. Then, a statistically-derived linear function of the input parameters is used to compute the linear discriminant function value at each grid point that passed screening. Lastly, a statistically-derived relationship between the linear discriminant function value and the corresponding past TC formation occurence frequecy at used to determine the probability of TC formation.

TC formation probability (TCFP) is computed for each 24-hr forecast interval (0-24hr and 24-48hr) based on the 24-hr averages of the input parameters. The cumulative probability of TC formation (CUMP) is computed using the formula:

CUMP(0-48h) = TCFP(0-24h) + TCFP(24-48h) – [TCFP(0-24h)*TCFP(24-48h)]

SUBREGION AVERAGES & SUMS:

To provide some time continuity of the product, the formation probability and the primary parameters used in the screening and discrimination analysis are summed (probabilities) or averaged (all other parameters) over 6, 3, 6, and 3 sub-basins for the Atlantic, Eastern Pacific, Western Pacific, and Indian Ocean basins, respectively. Time series products comparing the current and climatological parameters over the sub-basins are provided on the web site.

Color	Ocean color derived from MODIS for the large Pacific Basin, including Chlorophyll-a (shown in thumbnail) as well as selected close-up sectors
El Nino and La Nina	This site provides answers to basic questions such as: What are La Nina and El Nino; Frequently asked questions and impacts of El Nino. It also describes current conditions that include current information and forecasts as well as real time data and products, including satellite data.
Ice concentration, Global	The ice concentration product from SSM/I measures the percentage contcentration of ice over the oceans. Values exceeding 100 percent are considered erroneous. This product is updated once per day at 4 am EST. Click on a region to zoom in.
Ice, Global	Daily Sea Ice from MODIS. This global product may be a few days old, and the request format is in year and Julian day (there is a Julian day calendar on the request form). Click on an area in the global image to pop-up a 5km-resolution close-up of that region and other information.
Temperature, local areas SST	Near real time high resolution surface (land or sea) temperature products from MODIS. Not cloud cleared but when used with the global SST product below can provide valuable insight into mesoscale SST. Select day from the calendar on the sites home page, then desired MODIS area then LST from left banner. Also see CoastWatch site referenced above.
Temperature, Global SST	Global SST analyses combining satellite derived SST with NCEP global analysis. Previous times are also available.
Wind speed, Ocean surface	The wind speed product from SSM/I is a measurement of the wind speed over the oceans. Indeterminate data in the product below usually results from the inability to take accurate measurements from the polar ice caps and areas of rainfall. This product is updated every four hours, and may be clicked on for a zoom in sector.
Wind Velocity (speed and direction), Ocean surface	Global Winds from QUIKScat. Scroll down after accessing page and click on desired area of quikscat pass for 12.5 km resolution winds from either ascending or descending orbits. Also see CoastWatch site referenced to above.
