Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

FEWW New Hurricane Scale

FEWW New Hurricane Scale Makes Hurricane Classification More Meaningful!

FEWW’s New Hurricane Scale is based on the Saffir-Simpson Hurricane Scale and provides a more detailed definition of hurricane forces.

Size Description

To make the classification of tropical cyclones even more descriptive, FIRE-EARTH recommends the addition of following suffixes for storm size to denote the category:

  • Midget hurricanes (m). With the average radius from the storm’s center of circulation to its outermost closed isobar (ROCI) in four quadrants measuring less than two degrees of latitude [222.2 km or 138.1 miles.]
  • Small. Small Hurricanes (s).  ROCI measuring between 2 and 3 degrees of latitude [222km< ROCI< 333km]
  • Regular. Average Hurricanes (r). ROCI measuring between 3 and 6 degrees of latitude [333km< ROCI< 667km]
  • Large. Large Hurricanes (g). ROCI of between 6 and 8 degrees of latitude [667km< ROCI< 889km]
  • Monster. Very Large Hurricanes (x). ROCI of larger than 8 degrees of latitude [ROCI> 889km]

Example: Hurricane GRETA, with ROCI of 960km, the largest ever recorded Atlantic hurricane, which reached a maximum sustained winds of about 225km/h on November 5, 1956 may be represented as a Monster hurricane, or 4Ax category hurricane on the FEWW New Hurricane Scale.

Thought for the Day: Reoccurrences of Natural Phenomena

Posted by feww on July 18, 2008

“Hurricanes and wildfires are as essential to nature’s ‘housekeeping’ system as blood circulation is to maintaining homeostasis.”

“Nature does what it does best to maintain a livable planet. But she can’t be expected to save you from yourselves every time. If you build your dream cabin in the crater of an active volcano, in a forest prone to wildfires, on a beach in the path of hurricanes and tsunamis … nature may ‘misunderestimate’ your wisdom!” ~ A Member of Creating A Sustainable Future

Although cyclones take an enormous toll in lives and personal property, they are important factors in the precipitation system of places they impact because they bring much-needed precipitation to otherwise dry regions. Tropical cyclones also help maintain the global heat balance by moving warm, moist tropical air to the middle latitudes and polar regions. The storm surge and winds of hurricanes may be destructive to human-made structures, but they also stir up the waters of coastal estuaries, which are typically important fish breeding locales.

Will 2008 be year of the tornadoes, too?

Posted by feww on May 23, 2008

Tornadoes Wreak Havoc

About 105 people have been killed by tornadoes since the beginning of this year. According to the reports some 868 tornadoes have struck through May 18. The tally is on par with 2004, in which a record 1,819 tornadoes were reported, National Weather Service Storm Prediction Center, in Norman, Okla., said.

“It will be one of the biggest years when all is said and done,” said Harold Brooks, a meteorologist at the center. “It’s been very, very active and very unusual.” The 136 tornadoes reported in January 2008 were about 7 times higher than the January average of 19 for the 1953 to 2005 period. The February record at 232 was 11 times higher than the previous February average of 21 tornadoes.

“Our work suggests that the trend, the sign, is that conditions for severe weather will increase,” said Robert J. Trapp, an associate professor of atmospheric science at Purdue University. (Source)

A sequence of images showing the birth of a tornado. First, the rotating cloud base lowers. This lowering becomes a funnel, which continues descending while winds build near the surface, kicking up dust and other debris. Finally, the visible funnel extends to the ground, and the tornado begins causing major damage. This tornado, near Dimmitt, Texas, was one of the best-observed violent tornadoes in history.

This sequence of three photographs was taken by a member of the VORTEX project outside of Dimmit, TX on June 2, 1995. Known to some as the most studied tornado of all time, multiple movies, radar images, photographs, and damage observations were made for this tornado’s entire lifespan by members of the VORTEX team.

What about the hurricanes?

The 2008 Atlantic hurricane season will be active with up to 16 named storms, nine of which are expected to become hurricanes, the U.S. National Oceanic and Atmospheric Administration, NOAA, said on Thursday.

to Up to five of the hurricanes forecast for the season starting June 1 will be major ones ranging from Category 3 to higher with winds exceeding 180 km per hour, NOAA said in its annual forecast. (Source)
