dropsonde_mslp_estimate

tropycal.utils.dropsonde_mslp_estimate(mslp, surface_wind)[source]

Apply a NHC rule of thumb for estimating a TC’s minimum central MSLP. This is intended for a dropsonde released in the eye, accounting for drifting by factoring in the surface wind in knots.

Parameters

  • mslp (int or float) – Dropsonde surface MSLP, in hPa.

  • surface_wind (int or float) – Surface wind as measured by the dropsonde. This must be surface wind; this cannot be substituted by a level just above the surface.

Returns

float – Estimated TC minimum central MSLP using the NHC estimation method.
