Low Pressure Centers

Tropical Cyclones
These are warm-core systems fueled entirely by latent heat release from condensation over warm ocean waters (Sea Surface Temperature $> 26.5^\circ \text{C}$). They are characterized by a distinct central feature known as the eye (cyclone)/), a region of remarkably low pressure and sinking air. The [maximum sustained wind speed](/entries/… -

Wind Patterns and the Pressure Gradient Force
Wind/) flows toward the low center in response to the Pressure Gradient Force ($\text{PGF}$), which is defined as the negative gradient of pressure ($-\nabla P$). In the Northern Hemisphere, the Coriolis effect deflects this inflow/) to the right, resulting in the characteristic [counter-clockwise spin](/entries/counter-clockwi…
