Description

A core function for calculating convective parameters commonly used in the operational prediction of severe convective storms. Returns a vector of parameters.

Usage

1
sounding_compute(pressure, altitude, temp, dpt, wd, ws, accuracy = 2)

Arguments

pressure

pressure [hPa]

altitude

altitude [m] (can be above sea level or above ground level as function always consider first level as surface, i.e h = 0 m) altitude [metres]

temp

temperature [degree Celsius]

dpt

dew point temperature [degree Celsius]

wd

wind direction [azimuth in degrees]

ws

wind speed [knots]

accuracy

accuracy of computations where 3 = high (slow), 2 = medium (recommended), 1 = low (fast)

Value

Named vector of 100+ convective indices
