Does this also help Delta's outflow from a WISHE perspective? As you pointed out, PVS mixes in low theta-e air in the storm's environment; if that is gone, parcels conserving theta-e likely have a trajectory further out from the storm center.
Outflow is high up in the troposphere.
WISHE is heat exchange of the water to the air induced by high-speed winds.
This occurs at the ocean surface and the troposphere boundary layer.
The parcel trajectory comes from the cold pool over the CoC creating buoyancy.
The warm-core above the cold pool then slings the parcels away from the CoC as they move higher into the troposphere which creates the outflow.
Right but the trajectory is also dependent on it's theta-e in the WISHE model. The enthalpy exchange is isothermal, the ascent is pseudoadiabatic. Figured having low-entropy air mixed out would increase the buoyancy and this secondary circulation is enhanced which exacerbates stronger radial flow, increased enthalpy fluxes, etc, but could be thinking about it wrong.
I haven't heard about the relationship of theta-e with respect to WISHE.
Do you have a reference?
