Sentences with phrase «on atmospheric flow»

Atmospheric science professors Nate Brunsell and David Mechem in KU's Department of Geography are co-authors of a new study just published in the Proceedings of the National Academy of Sciences by an international research group that evaluated the effects of large wind farms on atmospheric flow and its implications for how much renewable energy the turbines can generate.

Improved competencies on atmospheric flow, together with the guidelines and best practices for the use of data, promises to become a key tool with reduced overall uncertainties for determining wind conditions.

Taken together, Palumbo says, the results offer a potential means of reconciling the geological evidence for flowing water on early Mars with the atmospheric evidence for a cold and icy planet.

After a painstaking analysis that modeled all known sources of acceleration for Juno, including the minute contributions from sunlight warming the spacecraft, Iess's team found a large north - south asymmetry in Jupiter's gravitational field — a clear sign of material flowing beneath the cloud tops on deep atmospheric winds.

Experiments carried out in the OU Mars Simulation Chamber — specialised equipment, which is able to simulate the atmospheric conditions on Mars — reveal that Mars» thin atmosphere (about 7 mbar — compared to 1,000 mbar on Earth) combined with periods of relatively warm surface temperatures causes water flowing on the surface to violently boil.

International trade in goods and services has a bigger impact on shifting the health burden of air pollution than atmospheric flows, a new study finds.

The preliminary results of this study have been on our website since the time the flooding happened, but now we have looked not only at the rainfall, but also the influence of anthropogenic greenhouse gas emissions on the atmospheric circulation and how this propagates from rainfall, to river flow down to the direct impact of flooded houses in the river catchment zones.

A NOAA website on atmospheric rivers contains this fascinating statistic that illustrates just how much moisture can be transported by winds in the mid-to-upper atmosphere: «A strong atmospheric river transports an amount of water vapor roughly equivalent to 7.5 - 15 times the average flow of liquid water at the mouth of the Mississippi River.»

Loose enough to be atmospheric, yet containing just enough detail to be both accurate and satisfying on closer more detailed inspection, his intuitive use of colour in bold flowing washes, is underpinned by his firm grasp of perspective and draftsmanship, complemented by a strong sense of place.

In sensitivity experiments the influence of removed orography of Greenland on the Arctic flow patterns and cyclone tracks during winter have been determined using a global coupled model and a dynamical downscaling with the regional atmospheric model HIRHAM.

We can estimate the atmospheric overturning from reanalyses which provide data on the flow over a range of vertical levels and on a global scale.

The chaotic nature of atmospheric solutions of the Navier - Stokes equations for fluid flow has great impact on weather forecasting (which we discuss first), but the evidence suggests that it has much less importance for climate prediction.

This is not the case with surface - to - air heat exchange (which involves evapo - transpiration, sensible heat flows, and radiation) or even within the troposphere where impacts of latent heating on atmospheric circulations are realized on scales ranging from hundreds of meters to thousands of kilometers.

Since coming to PNNL, he has led or been significantly involved in studies of effects of surface heterogeneity on boundary layer structure, of mesoscale atmospheric flows induced or modulated by complex terrain, of the simulation of dust emission by wind erosion, and of the capabilities of a variety of atmospheric instruments — including a mass spectrometer and wind profiling radar — for measuring atmospheric turbulence.

He quotes a textbook that derives the DALR in a section on climate dynamics, atmospheric flow.

-- Stephen, I would suggest that external factors influencing atmospheric pressure variations (& hence flow AND CLOUDS), which operate on more than one timescale, are largely responsible for what many choose to ascribe to «ocean cycles».

What is ACTUALLY happening now is that the atmospheric greenhouse effect is getting stronger; and at the same time the circulations of water and air and heat and cloud and so on around the globe are going on their merry chaotic way, meaning that we are going to have unpredictable short term variations while there is a continual flow of heat into the ocean from the energy imbalance between what is being emitted and what is being absorbed.

That rate of flow remains completely dependent on the atmospheric pressure which under current conditions causes evaporation to have a net cooling effect.»

My subfield of atmospheric and oceanic sciences is large - scale atmospheric dynamics — basically the fluid mechanics of atmospheric flows with horizontal scales of hundreds to thousands of kilometers (on Earth and Mars, at least).

Both a glass greenhouse and an atmospheric greenhouse lead to higher surface temperatures by blocking a flow of heat upwards, while having much less effect on the heat flow downwards.

(Because the extra thermal energy has lead to more intense flows in atmospheric and oceanic currents, which has resulted in more movement of and stress on the tectonic plates thus more and stronger earthquakes.

To be short on this: reservoirs have not the slightest influence on other reservoirs (including the atmospheric reservoir), if there were no flows / cycles between them.

Other proposed mechanisms confine the Arctic's influence on large - scale circulation changes to the troposphere, in which a warmer Arctic favors a wavier flow and more persistent atmospheric blocking, which often spawns extreme weather events58, 59.
