2. Pressure-wind relationship calculations for tropical cyclones

   en.wikipedia.org/wiki/Pressure-wind_relationship...

   The interchangeability of pressure and wind allows for the two to be used to give equivalencies for the public. [3] Pressure-wind relations can be used when information is incomplete, forcing forecasters to rely on the Dvorak Technique. [8] Some storms may have particularly high or low pressures that do not match with their wind speed.

3. Pressure system - Wikipedia

   en.wikipedia.org/wiki/Pressure_system

   A low-pressure area is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere. [1] The formation process of a low-pressure area is known as cyclogenesis. [2]

4. Low-pressure area - Wikipedia

   en.wikipedia.org/wiki/Low-pressure_area

   In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area . Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), [ 1 ] while high-pressure areas are ...

5. Tropical cyclone intensity scales - Wikipedia

   en.wikipedia.org/wiki/Tropical_cyclone_intensity...

   Any tropical cyclone that develops within the Southern Hemisphere between Africa and 90°E is monitored by Météo-France's La Réunion tropical cyclone centre (MFR, RSMC La Réunion). [24] A tropical disturbance is MFR's generic term for a non-frontal area of low pressure that has organized convection and definite cyclonic surface wind ...

6. Extratropical cyclone - Wikipedia

   en.wikipedia.org/wiki/Extratropical_cyclone

   The central pressure of the cyclone will lower with increasing maturity, while outside of the cyclone, the sea-level pressure is about average. In most extratropical cyclones, the part of the cold front ahead of the cyclone will develop into a warm front, giving the frontal zone (as drawn on surface weather maps) a wave-like shape. Due to their ...

7. Fujiwhara effect - Wikipedia

   en.wikipedia.org/wiki/Fujiwhara_effect

   Typhoon Parma (left) and Melor (right) interacting with each other in the Philippine Sea on October 6, 2009.. The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw(h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas.
