[Ref AC00-6B] What can you expect in Cumulus Cloud (Cu)? Indeed, there are 2 types of Cumulus Cloud (Cu): Cumulus with little vertical development (e.g fair weather cumulus) Towering cumulus (TCU) For Cumulus with little vertical development: turbulence Note: suppose no significant icing! For Towering cumulus (TCU) – cumulus with moderate/strong development: very […]

“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 […]
