Pacific Weather Patterns Explained

My wife, Vinni, has many duties on board, one of them is being our weather forecaster. She became intensely interested in weather, its causes and patterns when we studied our Yachtmaster Ocean. Her interest has continued out into the Pacific, where the weather simply doesn't act like it does in the Atlantic. Although an amateur, she has an in-depth grasp of why the Pacific weather behaves as it does.

She has written an article about this that has garnered praise from several who are quite knowledgeable about Pacific weather.

Since the Pacific is beginning to open up again - this knowledge may be useful for those planning a Pacific crossing.

here is a link:

Hope it will be some use

Re: Pacific Weather Patterns Explained

Minor points:

* no body of water on the planet is called the "Tasmanian Sea";

* the body of water south of Australia is the "Southern Ocean" (and it extends around the planet, being circum-polar or at least circum-Antarctica).

* Bob McDavitt has at least twice discussed the origin of the SPCZ and the role of the Andes in his blog. See:

https://metbob.wordpress.com/2019/06...-blog-16-june/
https://metbob.wordpress.com/2018/08/12/bob-blog-12aug/

* and Vinni might like to add a paragraph on the concept of the "subtropical ridge". I once used the term STR, without explaining its significance (assuming that every ocean sailor knows to avoid the STR), to a European sailor whom I later learned put his vessel smack on the STR and wondered why he moved little and slowly for a long time

That did not stop a paint manufacturer naming a colour "Tasmanian Sea".

True, but there is a body called the Tasman Sea, named for the Dutch navigator Abel Tasman (1603-1659), which lies between New South Wales and New Zealand. You can read about its unkindly nature in Smeeton’s book, Once is Enough, and among the various accounts of the annual Sydney to Hobart race. Also, the Southern Ocean’s northern boundary lies, by consensus, somewhere between 50 and 60 deg South Latitude.

Nicely done Vinni. "Tasmanian Sea" notwithstanding, I found it very informative and hopefully useful in the future.


Cheers,

Cheers,
Thank you, As Vinni noted, she is a sailor, not a professional meteorologist. She apologizes for any mistakes.

The guide is useful if you plan to sail the South Pacific
