Elephant in the Room- Ms. Sandy

Yankees...hurricane gets to coast and get converted to something else.

Big winter storm now.

Hurricane Sandy Discussion Number 30...Corrected
Statement as of 5:00 PM EDT on October 29, 2012

the convective structure of Sandy has deteriorated today...even as
the central pressure has continued to slowly fall...suggesting that
the convection is no longer driving the bus. The intensification
observed this morning was associated with strong winds occurring to
the southwest of the center...outside of the central core...and was
almost certainly due to baroclinic forcing. In addition...aircraft
data indicate that there are strong temperature contrasts very near
a modest residual warm core. Water vapor imagery indicates that
Sandy is becoming absorbed within a large mid-latitude cyclonic
circulation. All of these considerations lead US to conclude that
the most appropriate classification at advisory time is
extratropical. However...for continuity of service NHC will
continue to issue advisories through landfall. A Post-storm
analysis will re-examine the timing of extratropical transition.

We anticipates that the last NHC advisory on Sandy will be issued at
11 PM EDT tonight. Since all coastal tropical cyclone warnings have
been discontinued.

Baroclinity

In fluid dynamics, the baroclinity (sometimes called baroclinicity) of a stratified fluid is a measure of how misaligned the gradient of pressure is from the gradient of density in a fluid.[1][2] In meteorology a baroclinic atmosphere is one for which the density depends on both the temperature and the pressure; contrast this with barotropic atmosphere, for which the density depends only on the pressure. In atmospheric terms, the barotropic zones of the Earth are generally found in the central latitudes, or tropics, whereas the baroclinic areas are generally found in the mid-latitude/polar regions.

Areas of high atmospheric baroclinity are characterized by the frequent formation of cyclones.

Extratropical Cyclones

Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are a group of cyclones defined as synoptic scale low pressure weather systems that occur in the middle latitudes of the Earth (outside the tropics) not having tropical characteristics, and are connected with fronts and horizontal gradients in temperature and dew point otherwise known as "baroclinic zones".[1] Extratropical cyclones are the everyday phenomena which, along with anticyclones, drive the weather over much of the Earth, producing anything from cloudiness and mild showers to heavy gales and thunderstorms.

Good old low pressure area is what I take it to mean.

[Royal]

I think the mid west and east coast know what low pressure means for weather. What does it mean?

[Pigeon]

A low-pressure area, low or depression, is a region where the atmospheric pressure at sea level is lower than that of surrounding locations.

Wind is initially accelerated from areas of high pressure to areas of low pressure. This is due to density (or temperature and moisture) differences between two air masses. Since stronger high pressure systems contain cooler or drier air, the air mass is more dense and flows towards areas that are warm or moist, which are in the vicinity of low-pressure areas in advance of their associated cold fronts. The stronger the pressure difference, or pressure gradient, between a high pressure system and a low-pressure system, the stronger the wind. Thus, stronger areas of low pressure are associated with stronger winds.

The Coriolis force caused by the Earth's rotation is what gives winds within low-pressure systems their counterclockwise circulation in the northern hemisphere (as the wind moves inward and is deflected right from the center of high pressure) and clockwise circulation in the southern hemisphere (as the wind moves inward and is deflected left from the center of high pressure)

The conspiracy types have spun this thing in every direction. Sometimes a weather incident is just that, created by nature.

Fucking Nuts.

On ATS

"A shark was spotted swimming in what was the front yard of someone’s home. The high surf that had inundated some homes in brigantine beach, NJ, also brought in sea life – including the shark."

Had a dream last night of Shamu ( Killer Whale) eating my dog in my front yard. Freaky.

You mean this is not Created by Advanced Technology on a Sub Marine! LIES!

Created using HAARP to prevent (select one) *Obama voters : Romney voters* from voting next week. Maybe they should have waited a few days before they walked it in to the east coast.
