Insights into Tropical Tropopause Layer processes using global models
[1] The climatology of the Tropical Tropopause Layer (TTL) in two state-of-the-art general circulation models is compared with observations. Results indicate that global models are able to resolve key features of the TTL, including the mean state and the variability of temperature, ozone, clouds, and thermal structure. The agreement indicates that large-scale processes, and the large-scale effe...

متن کاملA Climatology of the Tropical Tropopause Layer
The tropical tropopause layer (TTL) is a transition region between the troposphere and the stratosphere. In this study the vertical extent of the TTL is diagnosed from radiosonde and ozonesonde profiles in the tropics and a climatology of this layer is presented. The radiative balance in the TTL is also characterized. The TTL is locally defined as extending from the level of the lapse rate mini...
متن کاملMaintenance of tropical tropopause layer cirrus
5 [1] A two-dimensional cloud resolving model with explicit bin microphysics is used to 6 study the maintenance of tropical tropopause layer (TTL) cirrus. Numerical simulations 7 using this model show that a TTL cirrus with a maximum radiative heating rate of 3 K/day 8 is able to self-maintain for as long as 2 days if it contains ice crystals whose initial 9 mean radius is smaller than about 5 ...
متن کاملA model of HDO in the tropical tropopause layer
Any theory of water vapor in the tropical tropopause layer (TTL) must explain both the abundance and isotopic composition of water there. In previous papers, we presented a model of the TTL that simulated the abundance of water vapor as well as the details of the vertical profile. That model included the effects of “overshooting” convection, which injects dry air directly into the TTL. Here, we...
