Question about increased activity.

[arcticfire]

I just had a strange thought pop into my head and figued I would ask.

Could the increase speed in the earths rotation due to the earthquake that caused the tsunami be partly responsible for the number of spin ups of TC's ?

My understanding is rudementrary on formation , but TC's are relient on the earths rotation to get going right ? So if you speed up the rotation , even minutly could that translate to more force applied to the low giving increased liklyhood of spin?

Granted we are talking about a miniscule increase in overall rotation of the earth , but wouldn't that translate to a lot of force around the equator when figuring something like drag effects on the atmosphere ?

I can hear what you are asking, but I did not know the Earth increased its rotational acceleration because of the tsunami. Pretty cool if it did. Can you provide a link to show the evidence please?

That said: I always thought that "tropical cyclones" formed as a difference in pressures accompied by all the factors that aid in the development, i.e., warm waters, little shear, along with warm and humid air. I could be showing my ignorance about this . . .

Interesting theory, but not feasible at all.

If that were the case, all the basins in the world would be experiencing greater number of tropical cyclones. This has not been the case.

The Atlantic is the exception rather than the rule...

According to some scientists, Earth's rotation increased by something less than a few nonoseconds. This was do, they theorize, that during the earthquake the Earth became just a tiny little more compacted.

Current Atlantic hyperactivity would be related more to the period of season over average that started in 1995 and will probably last to around 2030. During the short time tropical cyclone data has been gathered in the Atlantic there seems to be a pattern of 25 to 30 years in which the activity in the tropics is above normal and then for the same period of time it becomes below normal. We saw a period of above hurricane activity from the 1930s to the 1960s, then from the 1970s to the middle of the 1990s the overall activity in the Atlantic was below normal. There are some scientists that even believe that also there are periods of 500 years in which the Atlantic is overall, very active, and then another 500 years in which the overall activity is less than average. Of course, they believe that right now we are in a period of very high activity.

Hurricane research is a very young field, and right now we can't argue that the earthquake, or Global Warning, or anything induced is the cause for these extreme activity in the Atlantic. We need to wait for more years to know what is causing this hyperactivity for sure. Right now we can't for sure point to an enemy and say, "you are the one causing this super activity" simply because we don't have enough data.

In my naive opinion, I go with the pattern over the years!

I have to disagree with you here Hyper. The earth's speed has very little to do with increased cane's. However, since the spin is slightly and I mean just that slightly, the earth's core moving faster and the increased sun activity all play a role in earth's atmosphere. We have some unsual events occur, as well as unusual high CME'S. So his hypothesis is plausible.JMHO..

Thereafter, since Earth's atmosphere is GLOBAL, then the effects of increased sun activity will be felt worldwide and all the basin will experience above normal seasons. Which is not the case right now with the exception of the Atlantic Ocean.

Please!

"[T]he day correspondingly decreased by 2.68 millionths of a second. "

(from the linked article)


So the rate of the Earth's rotation has changed approximately 2.3 billionths of a percent.

And this is supposed to have affected tropical cyclones?
