Sentences with phrase «deep convection clouds»

Not exact matches

We suspect that water, the constituent of Saturn's deepest cloud deck, can suppress convection in the lighter hydrogen atmosphere for a period of decades, until finally buoyancy wins out and a large convective outburst ensues.

While the specific vertical profiles of these variables differ from region to region, the study showed that the moisture and vertical velocity anomalies, occurring about one hour before the triggering of convection, are better predictors of the clouds» transition to deep convection.

The researchers» novel approach identified anomalies in the cloud environmental conditions that are important to trigger the transition to deep convection.

The stability of the marine layer prevents deep convection, and thus stratiform clouds are formed.

Would it mean latent heat budget, deep / shallow convections, low - medium - high cloud cover are indifferent to the «hot spot» at 200 - 300 hPa?

Changes in convection and cloud formations through altered air moisture (CAPE) could have implications for the coupled mode mechanisms, as would a deeper thermocline (usually situated near the bottom of the warm surface layer).

In the tropics, where you have deep convection and vertically extensive cloud towers, you have reflective cloud tops that also emit energy to space very high up, resulting in two very large but opposing terms in the energy balance.

As the atmosphere humidifies and destabilizes, deep convection is eventually triggered, heating the entire column, while shallow clouds continue to be present.

The meeting will mainly cover the following themes, but can include other topics related to understanding and modelling the atmosphere: ● Surface drag and momentum transport: orographic drag, convective momentum transport ● Processes relevant for polar prediction: stable boundary layers, mixed - phase clouds ● Shallow and deep convection: stochasticity, scale - awareness, organization, grey zone issues ● Clouds and circulation feedbacks: boundary - layer clouds, CFMIP, cirrus ● Microphysics and aerosol - cloud interactions: microphysical observations, parameterization, process studies on aerosol - cloud interactions ● Radiation: circulation coupling; interaction between radiation and clouds ● Land - atmosphere interactions: Role of land processes (snow, soil moisture, soil temperature, and vegetation) in sub-seasonal to seasonal (S2S) prediction ● Physics - dynamics coupling: numerical methods, scale - separation and grey - zone, thermodynamic consistency ● Next generation model development: the challenge of exascale, dynamical core developments, regional refinement, super-parametrization ● High Impact and Extreme Weather: role of convective scale models; ensembles; relevant challenges for model development

In - depth analysis reveals that the model's shallow cumulus convection scheme tends to significantly under - produce clouds during the times when shallow cumuli exist in the observations, while the deep convective and stratiform cloud schemes significantly over-produce low - level clouds throughout the day.

Other feedbacks like clouds, (poleward and deep) convection may alter that in positive or negative ways, but that is exactly what the current debate between skeptics and warmers is about.

A heavy storm releases energy pushing the cloud top up to sometimes 20 km in deep convection and downdrafts increase with evaporative cooling with the downward flow converting to horizontal flow.

High - level cloud cover in the tropics with significant optical thickness is predominantly associated with deep convection, and clouds of this nature play the second most important role in accounting for model differences (Webb et al. 2006).

The ~ 26 C threshold for hurricanes exists because at colder temperatures, convection (cumulus clouds) can not get deep enough to sustain such storms.

The warm water evaporates from the ocean surface, and the light, warm and humid air rises, leading to deep convection in the form of towering cumulonimbus clouds and heavy precipitation.
