Context

  • New damage was reported in southern Japan, where Typhoon Nanmadol hit over the weekend.

 

Nanmadol

  • Typhoon Nanmadol is one of the biggest storms to hit Japan in years - and the 14th typhoon of the season. The name was contributed by Micronesia and refers to the Nan Madol archaeological site on Pohnpei.

 

Typhoon

  • A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones.
  • For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E).

Formation

Like any tropical cyclone, there are several main requirements for typhoon formation and development:

(1) sufficiently warm sea surface temperatures,

(2) atmospheric instability,

(3) high humidity in the lower-to-middle levels of the troposphere,

(4) enough Coriolis effect to develop a low pressure center,

(5) a pre-existing low level focus or disturbance, and

(6) a low vertical wind shear.
