“Typhoons”, “Cyclones”, “Hurricanes” – all are Tropical storms !

[Ref Understanding Weather & Climate, Books a la Carte Edition (6th Edition) #ISBN-13: 978-0321773227 #ISBN-10: 0321773225] Tropical storms have different names depending on where they occur Extreme Western Pacific –  Typhoons Indian Ocean and Australia – Cyclones Atlantic and Eastern Pacific – Hurricanes (Hurricanes are refer to any storm, regardless of location) In structure, these […]

Thunderstorms

The tremendous increase in temperature during a lightning stroke causes the air expand explosively and produce the familiar sound of thunder; Not all lightning produce sound – Heat lightning – lightning without […]

However, the stability of the air is determined in combination of moisture and temperature. Static stable air – […]

Localized Convection (lifting mechanisms)

[Understanding Weather & Climate, Books a la Carte Edition (6th Edition) #ISBN-13: 978-0321773227 #ISBN-10: 0321773225 CH 6 Cloud Development and Forms] Localized Convection Heating the air near the surface increase the buoyancy, the lifting causes the free convection   p.S- Localized Convection (lifting mechanisms) is one among four mechanisms lift air so that condensation and cloud formation can occur.
