Changes in weather patterns creating more severe storms

Jun 01, 2011 By John Harrington Jr.

(PhysOrg.com) -- A Kansas State University climate expert attributes the increase in the number and severity of tornadoes and severe storms in 2011 to a change in weather patterns.

John Harrington Jr., professor of geography, is a synoptic climatologist who examines the factors behind distinctive . He credits the increased tornado production this year to jet stream patterns in the . The patterns have created synoptic events such as the April tornado outbreak in Alabama and recent tornado in Joplin, Mo. While these events are not unprecedented, they are significant, he said.

"To put them in all in one year, that's what has people talking about this stuff," Harrington said. "The fact that this is happening all in one year and in a relatively short time frame is unusual."

Special circumstances are necessary for the creation of in the Great Plains, Harrington said. A humid atmosphere with moisture from the Gulf of Mexico and the right jet stream pattern coupled with surface convergence help to spawn a thunderstorm. Uplift from the jet stream helps to create the towering clouds associated with severe thunderstorms. Add a wind pattern set up with air filtering into the storm from the south at low levels, from the southwest at mid-levels and the northwest at higher levels, rotation of the begins and its possible for a tornado to form.

"Unfortunately in terms of death and destruction, we've had too many of those events this year," Harrington said.

Forecasting tornadoes far ahead of time differs from the more advanced hurricane and methods. The National Weather Service's Climate Prediction Center does not predict tornadoes, rather it attempts to predict jet stream patterns a month or so in the future.

In the wintertime the jet stream tends to flow above the southern United States. It migrates northward by the summertime. The area receiving the most tornadoes tends to shift with jet stream location as well. Oklahoma usually has a higher frequency of tornadoes in April, while Kansas experiences most of its tornadoes in May, Harrington said.

Synoptic patterns are different in autumn as the jet stream migrates back south, with much drier air across much of the U.S. While this does not preclude fall tornadoes from occurring, they are rare events. Connecting the surface conditions with the jet stream flow pattern helps a weather forecaster understand the likelihood for severe storms.

"That's pretty important in terms of understanding the kind of environment that will produce the necessary thunderstorms that rotate," Harrington said.

Extreme examples of weather have not been isolated to tornadoes. Heat waves, blizzards and have been increasingly more frequent or more severe according to U.S. data, Harrington said. These changes can be attributed to changes in the climate system.

The increase in severe weather events is drawing attention, he said.

"We have these good historical precedents for specific synoptic events, but they're starting to come more frequently together. That's what is very interesting, is that this weather system seems to be getting more variable."

Are almost certainly caused by our violently unstable Sun [1].

Cyclic changes in Earth's heat source - the Sun - induce changes in Earth's climate [2,3].

Why?

Solar wobble shifts the dense, energetic neutron star inside the Sun's diffuse, globe of waste products - the photosphere [4].

Oliver: Thank you very much for cluttering up this post with your meaningless garbage about neutron repulsion. This is an article about severe weather. Even if your observations were correct (which no one believes), you do not show a causal relationship to severe weather. What this paper does is point out that there are unusual conditions that are being identified. This climatologist is just reporting on observations. For you to try to cram your neutron repulsion and wobbling sun into this discussion should be embarrassing for you - but I know it won't be. Please show your direct link between a wobble in the sun and increased severe weather.

I would suggest reporting his post as inappropriate in hopes that the moderators realize OKM is being a nuisance. If he wants to write in his own blog, well and good, but he shouldn't be spamming Physorg for self-promotion.

OKM has jumped on the climate-denial bandwagon, but I have a suspicion that he doesn't really care that much about it. It's just given him a community that will actually back him, giving him a boost in promotion of his dubious physics.

"Are almost certainly caused by our violently unstable Sun. - OmaTard

You mean the "violently unstable sun" that has been proven to be unviolently stable for millions of years through isotopic analysis of ocean sediments?

Perhaps the Iron Sun that revolves around your home planet of Tardville is violently unstable, but here on earth, the sun we rotate around is remarkably stable.

Poor.....Poor.. OmaTard.

This is an article about severe weather.


Do you think neutron stars are dead nuclear embers?

Was the pulsar in the Crab Nebula recently found to be unstable?

Do you know that waste products from the Sun totally engulf planet Earth?

Why assume that Earth's constantly changing climate and its turbulent weather are independent of the Sun?

If you have not done so, I recommend that you read Stuart Clark's book about Richard Carrington's abrupt education on the violent nature of Earth's heat source in 1859.

"The Sun Kings: The Unexpected Tragedy of Richard Carrington and the Tale of How Modern Astronomy Began" {Princeton University Press, 2007] 211 pages

That violent event in September 1859 is described in the front book flap.

Hay Tard Boy... Do you seriously think our sun is a neutron star?

"Do you think neutron stars are dead nuclear embers?" - OmaTard

Sorry Tard boy. But the solar wind comes from the solar Corona and Photosphere and has the composition of those outer layers of the sun.

Those outer layers consist primarily of the principle component of the sun which is hydrogen. The "waste product" of the fusion of that hydrogen is held almost entirely in the core of the sun.

You might as well say that the earth is entirely surrounded by the "waste product" of the big bang.

In any case - ignoring your stupidity... The particle density of the solar wind is on average around 7 atoms per cm**3.

The particle density of air at STP is around 4x10**19 atoms per cm**3, which is 40 trillion million times more dense.

Yup. So violent that it caused an aurora.

Woo Hoo....
