Erm... no .. it's not.
Weather is impacted by water temps, as the temp of the water effects the temp of the air, and the temp of the air effects wind currents, which in turn
effects the disruption of average seasonal weather patterns.
La Nina cools the West Coast, this in turn creates cooler temps and wetter than normal seasons.. usually Winter and Spring specifically.
It warms the South East and into the North East, the alteration in the weather pattern pushes more rain into the plains states, which then in turn can
create severe storms into the Mid West and East Coast.
In Oregon and Washington it rained quite literally every day from December to June .. our temps average -10 below normal.
La Nina is particularly strong this year, meaning temps dropped more than average at the Equator.
Get an education. Research something before believing it. People scream about natural disaster because they are apparently more "frequent" .. this
is false.. the fact is that we build cities in stupid places, and because our population is continuously expanding, each disaster will effect more
people. Law of probability. No moronic Progressive has ever given me even an ounce of evidence to suggest anything to the contrary.
Apparently you are the one who needs to do the research- try starting with the NOAA:
Current Conditions As of mid-May 2011, SST anomalies have weakened to the point of reflecting cool ENSO-neutral conditions in the central and eastern
equatorial Pacific. For April the SST anomaly in the NINO3.4 region was -0.77 C, indicative of weak La Niña conditions, and for the
January-March season the anomaly was -1.01 C. Currently the IRI's definition of El Niño conditions rests on an index of SST anomalies, averaged
over the NINO3.4 region (5S-5N; 170W-120W), exceeding the warmest 25%-ile of the historical distribution, and similarly for La Niña relative to the
25%-ile coldest conditions in the historical distribution. The NINO3.4 anomaly necessary to qualify as La Niña or El Niño conditions for the
May-Jun-Jul and the Jun-Jul-Aug seasons are approximately (-0.50C, 0.45) and (-0.50, 0.45), respectively.
What is causing the enhanced low pressure systems that have affected not only the Pacific coast but also the mid US is a stronger than normal Jet
Stream that has been forced higher into the northern latitudes over a warmer north Pacific Ocean. The Jet Stream then has been looping deeply south
dragging cold northern latitude and upper atmosphere air down across the west coast and western US with it. This has been cooling the Pacific Coast.
Once over the mid US the lows behind the Jet Stream are pulling in warm, moist Gulf air that is creating massive storms. This 'loop' then has been
turning in a northerly direction- driving up over the eastern and northeastern states. This was strong enough last week to create a tornadic outbreak
This has been happening off and on all year - and the first effect from it was the Winter Blizzard.
Of course to mention this explanation would then open up the 'Oh, the pacific ocean is warming'? can of climate denial worms.
So lets just call it El Nino or La Nina - that'll fix everything.
And to your remark about 'cities expanding' and 'more people'.
That doesn't work with Tornadic outbreaks or floods.
People used to be more spread out across the countryside in 10 to 200 acre farms. People are now more tightly compacted in suburbs around city areas
and there are fewer people 'spread' across the country.
Picture this in your mind:
Set up a pattern of bowling pins scattered across an area and roll a ball at it.
Now set up a tight cluster of bowling pins and roll a ball at it.
Do you get it?
