Precipitation and Cloud Structure in Midlatitude Cyclones
Composite mean fields and probability distribution functions (PDFs) of rain rate, cloud type and cover, cloud-top temperature, surface wind velocity, and water vapor path (WVP) are constructed using satellite observations of midlatitude cyclones from four oceanic regions (i.e., the North Pacific, South Pacific, North Atlantic, and South Atlantic). Reanalysis surface pressure fields are used to ...
متن کاملBoundary-layer friction in midlatitude cyclones
Results from an idealized three-dimensional baroclinic life-cycle model are interpreted in a potential vorticity (PV) framework to identify the physical mechanisms by which frictional processes acting in the atmospheric boundary layer modify and reduce the baroclinic development of a midlatitude storm. Considering a life cycle where the only non-conservative process acting is boundary-layer fri...
متن کاملEffects Of Cumulus Convection On Rapidly Intensifying Cyclones
Our objectives are a) To describe the detailed structure of the air flow in a mature hurricane, b) To understand the vertical force balance in the eye and the eyewall, c) To investigate the presence of supergradient flow in hurricanes and the underlying processes, d) To study the surface wind structures during landfall, e) To investigate the transformation of a cold-core continental mesovortex ...
متن کاملEvidence of spray-mediated air-sea enthalpy flux within tropical cyclones
It has long been conjectured that spray ejected from the high-wind ocean surface enhances air/sea enthalpy fluxes, but a lack of observational data, particularly at wind speeds exceeding 20 m s−1, has prevented either confirmation or refutation of this hypothesis. The current study has two aims: first, to provide an estimate of surface enthalpy fluxes obtained from dropsonde data and second, to...
متن کاملOn the Applicability of Linear, Axisymmetric Dynamics in Intensifying and Mature Tropical Cyclones
The applicability of linearized axisymmetric dynamics to the intensification and structure change of tropical cyclones is investigated. The study is motivated by recent work that presented axisymmetric solutions to the linearized, non-hydrostatic, vortex-anelastic equations of motion (the so-called 3DVPAS model). The work called into question the importance of a recently proposed nonlinear, sys...
