Tornadoes Close To Record Low Level: ‘July are one of the lowest on record, according to NOAA’s Storm Prediction Centre’

Tornadoes Close To Record Low Level

Provisional tornado numbers up to the 30th July are one of the lowest on record, according to NOAA’s Storm Prediction Centre.
The figures are based on LSR’s, or Local Storm Reports. It usually takes about three months for tornadoes to be confirmed and graded, with some LSR’s discarded as either duplications or found not to be tornadoes.
The top chart uses percentiles, based on 1954-2012, so giving a longer historical perspective. As many smaller tornadoes were not even reported in earlier decades, the SPC adjust earlier years up to compensate.
Last year’s tornado numbers were also extremely low, which is interesting given the contrast in US temperatures between last year and this. The two GISS maps below show the Spring temperature anomalies for each year.
The SPC themselves admit they don’t understand how tornadoes form, but an important ingredient is the collision of cold, dry air and warm moist air. In 2012, most of the country, and certainly tornado alley, was consistently warm. This year, it has been consistently cold, even down to the gulf. By and large, the conditions needed for the collision of warm and cold air have not existed.

Now contrast the last two years with 2011, when tornadoes were near to record highs. The difference is very obvious.

Most tornadoes occur between April and July, so, fingers crossed, tornado numbers will remain at a very low level for the rest of the year.

Growing Antarctic Sea Ice Extent Breaking All Records

Antarctic Sea Ice Extent Breaking All Records

Antarctic sea ice extent at the end of July was the highest on record for that day, growing to 18.077 million sq km. The previous record of 17.783 was set in 2010, whilst the 1981-2010 average was 16.869.

Ice extent has been above average all year, and, according to NSIDC, is outside the 2 Standard Deviation range now.

Sea ice area also continues to run at well above average.

North Pole Sees Unprecedented July Cold – Arctic Sees Shortest Summer On Record — ‘Normally the high Arctic has about 90 days above freezing. This year there was less than half that’

Unprecedented July Cold – Arctic Sees Shortest Summer On Record

“Normally the high Arctic has about 90 days above freezing. This year there was less than half that,”  says Steven Goddard website.

“The Arctic ice extent is showing a remarkable recovery from the great oscillations of 2012,” says Guimaraes. “Compare with the previous years listed there, you’ll see that 2004 is the year that is closest to 2013 in terms of average temps during the summer.”
