Moisture–convection feedback in the tropics

Quarterly Journal of the Royal Meteorological Society, 2004
AbstractThis paper discusses the large‐scale moisture–convection feedback in the tropics, where spatial fluctuations of deep convection cause perturbations of free‐tropospheric moisture which, in turn, affect the spatial distribution of deep convection.

The diurnal cycle of tropical convection

Journal of Geophysical Research: Atmospheres, 1993
The diurnal cycle of tropical convection is investigated with global cloud imagery constructed from 11μm radiance measurements taken aboard six satellites. Four harmonics of the diurnal cycle are resolved in the cloud imagery with about 50 km horizontal resolution.

Gregarious Tropical Convection

Journal of the Atmospheric Sciences, 1993
Abstract A beat source with a vertical profile like that of observed tropical mesoscale convective systems (MCSs) is shown to cause, through inviscid gravity wave dynamics, upward displacement at low levels in a mesoscale region surrounding the heating.

Organization of tropical convection

2017
Atmospheric moist convection is an important source of uncertainty in current climate models. Compared to the resolved spatial scales, convective updrafts are small scale processes which, however, have an important influence on the atmospheric state. To determine their effect on the resolved scales, clouds are usually approximated as non-interacting ...

Coastal Convection in the Tropics

2017
Weather and climate models produce large rainfall errors in tropical coastal regions where the rain is often shaped by land-sea interaction like sea-breeze circulation systems. However, it has been difficult to quantify the contribution of these meso-scale interactions to the overall local rainfall.

Convective Fluxes in Tropical Cyclones

Journal of the Atmospheric Sciences, 1977
Abstract Vertical fluxes of mass, static energy and angular momentum in tropical cyclones and their environments are analyzed using composite rawinsonde data. Cumulus-scale eddy fluxes are derived using a spectral cloud model incorporating the effects of downdrafts, overshoot cooling, multiple-level cloud detrainment and ice-phase transitions.

Theory of tropical moist convection

2020
These lecture notes cover the theory of tropical moist convection. Many simplifications are made along the way, like neglecting rotation and treating the atmosphere as a two-dimensional fluid or even reducing the atmosphere to two columns. We can gain an immense amount of insight into the real atmosphere by studying these toy models, including answers ...

The Interaction of Waves and Convection in the Tropics

Journal of the Atmospheric Sciences, 2003
Interest in tropical waves and their interaction with convection has been rekindled in recent years by the discovery, using satellite infrared data to track high clouds, that such waves closely display the dispersive properties of linear, inviscid wave theory for an atmosphere with a resting basic state and equivalent depths between 12 and 60 m.

Numerical studies of tropical convection

2013
Idealized numerical model experiments are presented to investigate the convective generation of vertical vorticity in a tropical depression. The calculations are motivated by observations made during the recent PREDICT field experiment to study tropical cyclogenesis, and by a desire to understand the aggregation of vorticity debris produced by deep ...
