Sentences with phrase «atmospheric convection»
"Atmospheric convection" refers to the way heat is transferred from the Earth's surface to the atmosphere. It happens when the air near the ground gets heated by the Sun, becomes less dense, and rises up. As it rises, it cools down and then sinks back down, creating a continuous circular cycle of upward and downward air movement. This process helps distribute heat, moisture, and air pollution throughout the atmosphere, shaping weather patterns. Full definition
The strength of the vertical movement is controlled by the same factors that control atmospheric convection elsewhere.

Deep moist atmospheric convection controls the development of major weather systems like hurricanes, drives the global transport of energy within the climate system and strongly influences the uncertainty of projected climate change.
The WP1 team will focus on improving the parameterisation of atmospheric convection and its coupling with the large scale tropical climate system.
More information: Miyamoto, Y., Kajikawa, Y., Yoshida, R., Yamaura, T., Yashiro, H. & Tomita, H. Deep moist atmospheric convection in a subkilometer global simulation.
In the future, Romps plans to look at the distribution of lightning - strike increases around the U.S. and also explore what lightning data can tell climatologists about atmospheric convection.
The sand frequently hitches a ride on atmospheric convection currents and travels as far south as the tropical Atlantic and west to the Caribbean Sea.
Normally, this connection is due to the aforementioned atmospheric convection and rainfall, but during the summer and fall of 2014, when those warm waters should have produced rainfall and pushed El Niño along, the atmosphere remained relatively dry.
The new model also suggests that the region's famous thunderstorms may become less common, as the decreased rain is associated with increased stability in the lower - to - middle troposphere and weakened atmospheric convection.
Just as an El Niño produces a hotter Equator in the Pacific Ocean and generates more atmospheric convection, so there might be a subnormal mode that decreases heat, convection, and evaporation.
Will the sensitivity of the atmosphere to the primary mechanism at the heart of El Niño — that is, feedback between the higher sea temperatures and slowing trade winds, leading to atmospheric convection over the central Pacific — continue in the future?
Furthermore, the majority of the Earth's precipitation falls in the tropics and is a direct result of atmospheric convection; it is therefore a key area for improving ESMs representation of the earth system.
For the past few years, Houze has filled a valued role as a collaborator with PNNL staff scientists, advancing the science of clouds and sharing his legacy of transformative research influencing how meteorologists and climatologists think about atmospheric convection.
«During the 1997 — 1998 El Niño, observations indicate that the SST increase in the eastern tropical Pacific enhances the atmospheric convection, which shifts the upward motion to further south and breaks down low stratiform clouds, leading to a decrease in low cloud amount in this region.
Further analysis reveals that overlying surface evaporation and atmospheric convection are modulated as a result of these forced changes to the temperature of the upper coastal Atlantic Ocean.
In the future, Romps plans to look at the distribution of lightning - strike increases around the U.S. and also explore what lightning data can tell climatologists about atmospheric convection.
This is incorrect because about half of the additional delta eK is a result of atmospheric convection that causes friction within the system and in contact with the earth's surfaces.
How can one arrive at a level of certainty exceeding 90 % about any aspect of the Earth's climate whilst attributing a value of zero to all the main (and obvious) factors namely the sun, the oceans, evaporation and condensation, clouds and atmospheric convection.
This leads to further warming as this feedback loop amplifies the phenomenon and ensures that deep atmospheric convection and rainfall patterns are maintained in the central equatorial Pacific.
In association with El Niño, the heat redistribution in the ocean creates a major reorganization of atmospheric convection, severely disrupting global weather patterns from Australia to India and from South Africa to Brazil.
As the central part of the Pacific warms up during El Niño, the atmospheric convection that normally occurs over the western warm pool migrates to the central Pacific.
