Abstract: Based upon Reed-Recker's (1971) composite easterly wave and the associated cumulus cloud population determined by Cho and Ogura (1974), the effects of cumulus cloud on the large-scale moisture distribution are studied in ...

Abstract: The horizontal momentum exchange process between cumulus clouds and their environment are examined. A general formula is also derived for the rates of entrainment and detrainment of momentum of a cumulus cloud ensemble. ...

Abstract: Effects of the life cycles of cumulus clouds, on the large-scale heat and moisture equations are derived by introducing a cloud distribution function which describes the cloud fractional coverage distribution in terms of ...

Abstract: Some statistical properties of homogeneous and stationary shallow cumulus cloud fields are studied. The work is motivated by the observation that the number of cumulus clouds in a large-scale tropical weather system is ...

Abstract: Dynamic processes of cumulus clouds which may produce significant horizontal eddy transport of vertical vorticity in the tropical atmosphere are discussed. It is shown in this paper that horizontal eddy transport of vorticity ...

Abstract: A two-dimensional semigeostrophic frontogenesis model is used to study meso-? scale potential vorticity anomalies as a possible cause for rainbands in midlatitude cyclones. The model includes water vapor and allows the ...

Abstract: The effects of cumulus heating and the possibility of CISK in extratropical latitudes are explored by combining the Eady model of baroclinic instability with wave-CISK. For perturbations about a state of rest, there is no ...

Abstract: The mechanism of moist potential vorticity (MPV) generation in a three-dimensional moist adiabatic and frictionless flow is investigated. It is found that MPV generation is governed by baroclinic vectors and moisture ...

Abstract: The effects of different moisture distributions on the generation of moist potential vorticity (MPV) in extratropical cyclones are examined by numerical simulations. These sensitivity experiments show that low-level negative ...
