Formation of large (≃100 μm) ice crystals near the tropical tropopause
Recent high-altitude aircraft measurements with in situ imaging instruments indicated the presence of relatively large (≃100μm length), thin (aspect ratios of ≃6:1 or larger) hexagonal plate ice crystals near the tropical tropopause in very low concentrations (<0.01 L−1). These crystals were not produced by deep convection or aggregation. We use simple growth-sedimentation calculations as well ...
متن کاملInteractive comment on “Aircraft measurements of microphysical properties of subvisible cirrus in the tropical tropopause layer” by R. P. Lawson
This paper describes observations of subvisible cirrus (SVC) clouds with the NASA WB-57F aircraft during the Costa Rica Aura Validation Experiment (CR-AVE) in 2006. SVC clouds were encountered and characterised with state-of-the-art optical array imageing probes in extended areas of the tropical tropopause layer with temperatures as low as −90◦C. Nearly spherical crystal shapes were measured fo...
متن کاملConvective formation of pileus cloud near the tropopause
Pileus clouds form where humid, vertically stratified air is mechanically displaced ahead of rising convection. This paper describes convective formation of pileus cloud in the tropopause transition layer (TTL), and explores a possible link to the formation of long-lasting cirrus at cold temperatures. The study examines in detail in-situ measurements from off the coast of Honduras during the Ju...
متن کاملHow do the water vapor and carbon monoxide ‘‘tape recorders’’ start near the tropical tropopause?
[1] This paper evaluates geo-seasonal relationships in tropical deep convection using radar and infrared data from Tropical Rainfall Measuring Mission (TRMM), near tropopause thin clouds from Stratospheric Air and Gas Experiment (SAGE) II, water vapor and carbon monoxide (CO) from the Earth Observing System (EOS) Microwave Limb Sounder (MLS), and the tropopause temperature from National Center ...
متن کاملThe heat balance of the tropical tropopause, cirrus, and stratospheric dehydration
If tropical tropopause cirrus lie above convective anvils with tops above about 13km, then net radiative cooling from the cirrus can be produced that is large enough to offset significant subsidence heating, even at the lowest temperatures observed in the tropics. Cirrus clouds near the tropopause are strongly heated by radiation unless they lie above convective anvil clouds. Radiative relaxati...
