CAPESConvective available potential energy shear

CAPE-SHEAR parameter is a product of wind shear and sqrt(CAPE):

CAPE-SHEAR parameter = wind_shear * sqrt(CAPE)

wind_shear denotes bulk shear which is a vector difference of winds at two different heights in the atmosphere and the second term sqrt(CAPE) is proportional to the maximum vertical velocity in convective updraughts.

PTYPEPrecipitation type

Describes the type of precipitation at the surface at the validity time. A precipitation type is assigned wherever there is a non-zero value of precipitation in the model output field (however small). The precipitation type should be used together with the precipitation rate to provide for example indication of potential freezing rain events. Precipitation type (0-8) uses WMO Code Table 4.201

Values of ptype defined in the IFS:

  • 0 = No precipitation
  • 1 = Rain
  • 3 = Freezing rain (i.e. supercooled)
  • 5 = Snow
  • 6 = Wet snow (i.e. starting to melt)
  • 7 = Mixture of rain and snow
  • 8 = Ice pellets

I-iii Tropical cyclones tracks

Tropical cyclones tracks products are provided in BUFR code free of information charge.

Tropical cyclone tracks will only produce data when a cyclone is forecast.
