Abstract:
AbstractA large‐eddy simulation (LES) was performed for a Hector thunderstorm observed on 30 November 2005 over the Tiwi Islands. On that day, ice particles reaching 19‐km altitude were measured. The LES developed overshooting updrafts penetrating the stratosphere that compared well with observations. Much of the water injected in the form of ice particles sublimated in the lower stratosphere. Net hydration was found with a 16% increase in water vapour. While moistening appeared to be robust with respect to the grid spacing used, grid spacing on the order of 100 m may be necessary for a reliable estimate of hydration.
