Cyclostrophic winds
WebWinds are driven by forces acting on air. But these forces can be altered by heat and moisture car - ried by the air, resulting in a complex interplay we call weather. Newton’s laws of motion describe how forces cause winds — a topic called dynamics. Many forces such as pressure-gradient, advection, and frictional drag can act in all directions. WebUsing these observations and cyclostrophic balance, researchers were able to estimate the winds inside the tornado at between 52 and 130 m/s (116 and 291 mph), a range that is broadly consistent with the winds …

WebThe cyclostrophic wind is a balance between the Pressure Gradient Force (PGF) and the outward fleeing centrifugal force. A cyclostrophic wind also tends to have a “tight” curvature compared to curvatures within … Webwind field using the cyclostrophic approximation [Chub and Yakovlev, 1980; Seiff, 1983; Newman et al., 1984; Limaye,1985;Roos-Serote et al., 1995; Zasova et al., 2007]. These …
WebBy definition, a cyclostrophic wind exists when the pressure gradient force is balanced by the centrifugal force alone. This exact situation rarely exists, but is so nearly reached in some situations that the small Coriolis effect … WebOct 17, 1997 · Cyclostrophic winds confined to a jet near Triton's northern or southern limbs (or both) could also be responsible for the details of the light curve, but such winds are required to be slightly supersonic. Hazes and clouds in the atmosphere are unlikely to have caused the asymmetry in the light curve.
