[1] Because clouds play such a significant role in climate, understanding their responses to climatic temperature changes is essential to determining the overall impact of a given climate forcing. Cloud liquid water path (LWP) over tropical and midlatitude oceans has been observed to decrease with increasing cloud temperature. The presence of an ice sheet over the Arctic Ocean alters the energy...

The noise, radiated from the tailpipe of automotive exhaust ducts, is affected by the jet flow leaving the exhaust and by its surrounding geometry. The current work extends existing studies of sound radiation from a jet pipe with radiation over a rigid ground surface and relies on a numerical study. A simplified approach is used where the mean flow properties behind the tailpipe are calculated ...

Turbulent fluids are frequently observed to spontaneously self-organize into large spatial-scale jets; geophysical examples of this phenomenon include the Jovian banded winds and the earth’s polar-front jet. These relatively steady large-scale jets arise from and are maintained by the smaller spatialand temporalscale turbulence with which they coexist. Frequently these jets are found to be adju...

Abstract Tropical cyclones (TCs) propagating into baroclinic midlatitude environments can transform extratropical cyclones, in some cases resulting high-impact weather conditions far from the tropics. This study extends analysis of transition (ET) changes multiseasonal global simulations using Model for Prediction Across Scales–Atmosphere (MPAS-A) under present-day and projected future conditio...

Midlatitude weather and climate are dominated by the jet streams and associated eastward moving storm systems. Occasionally, however, these are blocked by persistent anticyclonic regimes known as blocking. Climate models generally predict a small decline in blocking frequency under anthropogenic climate change. However, confidence in these predictions is undermined by, among other things, a lac...

Persistent superrotation is seen in the atmospheres of other terrestrial bodies (Venus, Titan) but not in that of present Earth, which is distinguished by equatorial easterlies. Nevertheless, superrotation has appeared in numerical simulations of Earth’s atmosphere, from two-layer models to multilevel comprehensive GCMs. Simulations of warm climates that generate enhanced tropical convective va...

numerical study has been carried out for slot air jet impingement cooling of horizontal concentric circular cylinders. the slot air jet is situated at the symmetry line of a horizontal cylinder along the gravity vector and impinges to the bottom of the outer cylinder which is designated as θ=0°. the outer cylinder is partially opened at the top with width of w=30mm and is kept at constant tempe...

A novel neuro-based method is introduced to solve the laminar boundary layer and the turbulent free jet equations. The proposed method is based on cellular neural networks, CNNs, which are recently applied widely to solve partial differential equations. The effectiveness of the method is illustrated through some examples.
