convection, in both day and night and during two times <strong>of</strong> year. The cooling rate is<br />
estimated to be around –7 K/day (potential temperature units) at 100 hPa during<br />
convection. While I cannot unambiguously assign a cause to this cooling, I do not<br />
believe it arises from radiation from either thick or thin clouds.<br />
I do show that the mixing-in <strong>of</strong> cold air from overshooting convection is a<br />
potentially reasonable explanation for the cooling. This air detraining from<br />
overshooting deep convection is not only cold but also might be very dry, and so might<br />
also play an important role in determining the humidity level in the TTL and in the<br />
lower stratosphere.<br />
