Pressure gradient force of wind Pressure differences must create a force in order to drive the wind. This force is the pressure gradient force. The force is from higher pressure to lower pressure and is perpendicular to isobars or contours. Whenever a pressure difference develops over an area,...
We experience these air currents as wind. The force driving these currents caused by the difference in pressure between the two regions. This is called the pressure gradient force. Air masses moved by pressure gradient force transfer heat by convection as cooler gas particles move into regions ...

The method adopted in deriving the geostrophic and gradient wind relations, that of specifying a wind field and deriving the pressure field from it, is extended to find pressure fields for other flow patterns. The motion is referred to contours of isobaric surfaces and the analysis is limited ...
If the imaginary slices were made of an extensible elastic material (like slices of rubber), shearing would also result in extension in the flow direction and uneven compression in the other two directions. So, when an (elastic) polymer solution or melt flows along a pressure gradient, it is...
The response of the surface mean wind vector to the synoptic pressure gradient was statistically calculated over the region of central Japan. The response was examined as related to the thermal effect, caused by daytime heating and nocturnal cooling in the surface layer. In the process of vector...

Alexander Rashkovan, in Progress in Energy and Combustion Science, 2008 When a fluid flows through a converging nozzle it experiences an average pressure drop. A higher convergence results in a steeper pressure gradient. In addition, due to the turbulent nature of the flow, the pressure ...
continentpressure gradientwhich is the main driving force of the ASM, is larger. However, the weakening of the continental heat low after the end of the 1970s reflects a decrease in the thermal difference between the ocean and continent, and the ASM also exhibits a corresponding weakening ...
