Zulu Time, and Weather Bloggers

In the NOAA and other hurricane and weather reports, they commonly notate Greenwich Mean Time with a suffix Z (or sometimes GMT), and spoken as "Zulu". The military, aviation, and commercial shipping commonly operate on Zulu time.

Why "Zulu"?  The story goes back to the great navigator, mathematician, and Salem, MA sea captain Nathaniel Bowditch (1773-1838), author of The American Practical Navigator - also known as "The Sailor's Bible" - which remains in use today. He divided up the world's time zones, one hour per 15 degrees of longitude, assigning each one a letter of the alphabet. Longitude 0, running through Greenwich, England received the Z. That story is here. 

Jean Lee Latham wrote the classic Carry On, Mr. Bowditch, which I remember fondly from 6th Grade, and which, along with Richard Henry Dana's Two Years Before the Mast, nurtured my love and respect for the sea and ships.

For weather bloggers, we like Weather Underground, and Stormtrack for big storms.
