- 3260 - HURRICANES - are worse than tornados! Computer models have shown that rising sea surface temperatures resulting from global warming could create more and more severe hurricanes. Global Warming is a trend linked to our burning of fossil fuels.
----------------------- 3260 - HURRICANES - are worse than tornados!
-
- New Orleans and Biloxi have certainly felt the wrath of the Nature’s worst in sky born forces. Between wind, earthquake, volcano, drought, flood and fire Nature is the unequivocal boss. In sheer magnitude and power hurricanes have the unmatched wind power.
-
- Tornados are a close second. They tend to happen between March and May, then hurricanes take over between June and November. Hurricanes start out as tropical storms, or cyclones, a low-pressure weather system where the core of the storm is warmer than the surrounding atmosphere.
-
- As the huge mass of moist air rises a spiral motion results. This is called the “Coriolis Effect” and it is caused by the Earth’s rotation. As the moist air rises it condenses emitting latent heat providing even more energy to the storm. When water turns from gas water vapor to liquid water it releases latent heat.
-
- The low pressure area occurs at the center of the storm, the eye of the storm, and it can be 6 to 7% lower than the rest of the system. The hurricane travels west across the Atlantic Ocean in the direction of the prevailing trade winds. (Typhoon is the Pacific Ocean name for a hurricane.)
-
- Hurricanes can have wind power of 150 mph with wind gusts up to 200 mph. That wind speed can send loose debris flying through the air like a barrage of missiles.
-
- Tornados can have wind power up to 320 mph, half the speed of sound. That wind speed can fling cars 100 yards in the air and level a house to its foundation.
-
- Tornados are a few dozen yards to several hundred yards across. Some have been as much as a mile wide at the ground point. Their swath of destruction can be hundreds of miles long.
-
- Hurricanes by comparison are huge. That is where their power comes from. They can be 200 to 300 miles across, some as massive as 700 miles wide.
-
- Tornados tend to occur over flat terrains like the plains of US and Australia. A typical year in the US will experience 800 tornados. Hurricanes in the US average only a dozen a year. The forecast for a typical year is 18 to 21 tropical storms, 11 hurricanes, 5 to 7 would do major hurricane damage. Katrina and Ida is certainly among those “major” hurricanes.
-
- Hurricanes are numbered one through five to designate their severity.
-
1 = 74 mph winds 4 feet surge
-
2 = 96 6
-
3 = 111 9
-
4 = 131 13
-
5 = >155 >18 feet surge up to 500 yards from shore requiring evacuations up to 10 miles from the shoreline. Number 5 is deemed catastrophic in severity.
-
- Tornados are number one through five also, since level 6 is not expected to ever occur.
-
0 = < 72 mph winds
-
1 = 73
-
2 = 113
-
3 = 158
-
4 = 207
-
5 = 281
-
6 = > 319 mph winds never expected
-
- The fastest tornado winds recorded is 440 feet per second, 300 mph. The center of a tornado can drop in pressure by 10%. This has the effect of imploding whatever it is on top of.
-
- When Hurricane Andrew struck south Florida it left $36,000,000,000 in damage. In 1974 148 tornados crossed 13 states and left $600,000,000 in damages.
-
- Tornados on average kill 100 US citizens each year. A tornado in 1925 killed 695 people, injuring 2,207, destroying 15,000 homes across Missouri, Illinois, and Indiana.
-
- The Hurricane in 1928 killed 1,836 people in Florida. In 1999 Hurricane Floyd caused 56 deaths. In 1991 the hurricane that struck Bangladesh killed 140,000 people. Hurricanes are definitely the “badest“.
-
- Tornados release energy equivalent to two large nuclear reactors. Hurricanes generate power equal to the rate of half of all the electrical production of the entire world at a given time.
-
- For hundreds of years hurricanes were named after the particular saint’s day on which they occurred. “Huracan” is the West Indian “god of storms”. The US Army began naming hurricanes after women during WWII.
-
- In 1979 political correctness required that the names alternate between female and male names. The names are recycled after five years unless they cause a great deal of devastation and damage, for which the name is retired.
-
- Names are selected in alphabetical order except names beginning with Q,U,X,Y,Z. Katrina’s name was used in 1993 and 2005 and definitely needs to be retired in 2005.
Ida in 2021 also needs to be retired.
-
- Computer models have shown that rising sea surface temperatures resulting from global warming could create more and more severe hurricanes. Global Warming is a trend linked to our burning of fossil fuels.
-
- It is not nice to mess with Mother Nature!
