Harvey and Irma are totally different monsters
completly.
Harveys destructure was a result of him stalling out in forward motion basically stood still for days
Sadly he stalled with half his tushie in the Gulf - if you think of a hurricane as a clock 9-3 AM was over land - they rain out over land.but the part from 3 in afternoon to 9 hung out over the gulf, continuing pulling up water then dumping out of land - over and over.
water = fuel. if you visualize the eye as the canister in your vacuum that is what the yey is basically doing . Sucking water up from the ocean.
When it get to a certain height it then spins out kinka like the water spinning out of your washer.
The higher the clouds the more water - its colder so when it comes down cold mixes with warm creating moisture.
Some of the monsters have cloulds at 50,000 feet.
Forward movement has drawbacks and benefits
Faster foward motion increases energy over land, so flooding (inland ) is much less an issue. So damage to building is more in faster forward moving storms casue there is more energy.
in terms of nature design they are for redistribution of water on the planet.
Fl did pass a law requring gas stations to have back up generators for pumping purposes.
For Irma the capacity to move after is from debris all over the roads not flooding.
In Harvey basically in the Rockport area we saw catastrophic roof and building structe damage.
Storm surge results in the most deaths - and the storm surge areas area are the only areas that can be evacuatedm cause the coastal areas there are predictive values , based on intensity.
Visually storm surge is like if your a pool, take your hand and swish it across the top of the water you will make a wave , the harder you swing your hand the bigger the wave,
The storm surge - much smaller event obviously visually is like the huge tsunami
the winds "pile" up massive amounts of water on top of the regular "ocean"/
As it landfalls it gets shallower resulting in the piled above water to rise higher and higher.
If you go back to clock the worst surge is in the noon to 3 quadrant. Becasue you have the band swirling around counterclockwise, wound tight around the eye,
But at that part noon to 3 you have the swirling plus forward movement all of it pushing it inward.
The converse if true from the 6AM to 9 am quadrant casue the winds are going the opposite the direction.
It can also be visulized as pizza with 4 slices.
That is why after the eye everything happens from the opposite direction than from before the eye comes over whatever area it does,
The eye is also like a rolled up sheet of paper. Often whereever the eye is directly over head it gets totally sunny and bright, if directly over you can look up and see blue skies and sunshine.
The eye is creepily silent nothing is moving everything is cleaned out.
That is basically what they doing
