Diurnal variation of upper tropospheric humidity and its relations to convective activities over tropical Africa
Diurnal variations of upper tropospheric humidity (UTH) as well as middle tropospheric humidity (MTH) were examined in conjunction with the diurnal cycle of convection over tropical Africa and the adjacent tropical Atlantic Ocean using Meteosat-8 measurements. Cloud and humidity features were also tracked to document the diurnal variations of humidity and clouds in the Lagrangian framework. A d...
متن کاملOvershooting convection in tropical cyclones
[1] Using infrared satellite imagery, best-track data, and reanalysis data, tropical cyclones are shown to contain a disproportionate amount of the deepest convection in the tropics. Although tropical cyclones account for only 7% of the deep convection in the tropics, they account for about 15% of the deep convection with cloud-top temperatures below the monthly averaged tropopause temperature ...
متن کاملComparison of Cirrus Cloud Radiative Properties and Dynamical Processes at Two Atmospheric Radiation Measurement Sites in the Tropical Western Pacific
Upper tropospheric humidity plays an important role in the formation and maintenance of tropical cirrus clouds. Deep convection is crucial for the transport of water vapor from the boundary layer to the upper troposphere and is responsible for the formation of anvil cirrus that can spread horizontally over considerable distances and persist for several hours. In addition, recent studies have li...
متن کاملDiurnal cycle of convection, clouds, and water vapor in the tropical upper troposphere: Satellites versus a general circulation model
[1] Global high-resolution (3-hourly, 0.1 0.1 longitude-latitude) water vapor (6.7 mm) and window (11 mm) radiances from multiple geostationary satellites are used to document the diurnal cycle of upper tropospheric relative humidity (UTH) and its relationship to deep convection and high clouds in the whole tropics and to evaluate the ability of the new Geophysical Fluid Dynamics Laboratory (GF...
متن کاملThe influence of convective outflow on water vapor mixing ratios in the tropical upper troposphere An analysis based on UARS MLS measurements
The source of increased water vapor mixing raregions of convective outflow. These studies dealt with varitios over the central and eastern tropical Pacific region during ations in relative humidity over a broad region of the tropthe 1992 E1 Nifio event is examined using measurements of ical upper troposphere (i.e., 200-500 hPa). Presently, it is upper tropospheric water vapor provided by the Mi...
