(Umiat, about 60 miles south of Prudhoe Bay and 200 miles southeast of Barrow has intermittent records from the later 40s to the turn of the century showing a 92 ºF reading on July 14, 1993 and many
daily record highs in the upper 80's.)
In fact, July had four times as
many daily record highs as record lows, according to meteorologist Guy Walton, who keeps track of such streaks using NOAA's data.
U.S. daily record high temperatures continued to surge into the end of March, with new heat records overwhelming cold records by the incredible ratio of 35.3 to 1.
The heat drove a record - setting ratio of
daily record highs vs. record lows and sped the arrival of spring in some areas by up to four weeks.
Antarctic sea ice extent increased rapidly through June and early July, and reached
new daily record highs through most of this year.
While equity investors
enjoy daily record highs in the popular benchmarks, I continue to patiently wait in low yielding cash and cash equivalents (granted, yields are thankfully moving higher).
However, you'll notice that shorter time periods will have much more lopsided ratios, including this year
when daily record highs are outnumbering daily record lows 9 - to - 1.
Meehl and his colleagues then used temperature simulations from the Community Climate System Model to
compute daily record highs and lows under current and future atmospheric concentrations of greenhouse gases.
As of Friday morning, NOAA's U.S. Records site had compiled 4492
daily record highs for February 2017, against a mere 29 daily record lows, for a lopsided highs - to - lows ratio of 155 - to - 1.
For instance, a study published in the journal Geophysical Research Letters in 2009, found that
daily record high temperatures occurred twice as often as record lows over the prior decade across the continental United States.
In 2009, Guy coauthored a high - profile paper in Geophysical Research Letters with lead author Gerald Meehl (National Center for Atmospheric Research), showing that
U.S. daily record highs have increasingly outpaced daily record lows since the 1980s.
For November 2016, the ratio
of daily record highs to lows was a stunning 48 - to - 1 across the country, the highest in the NCEI records, according to meteorologist Guy Walton, who tracks these records.
«In addition, 11
daily record high temperatures were set as were 8 daily record warm low temperatures and 2 monthly record warm low temperatures.»
Daily record highs have outpaced record lows at a rate of 5:1 this year, including an insane November when daily high maximums and minimums outpaced their low counterparts by a whopping 44:1 according to the National Centers for Environmental Information.
If nations continue to increase their emissions of greenhouse gases in a «business - as - usual» scenario, the U.S. ratio of
daily record high to record low temperatures would increase to about 20 to 1 by midcentury and 50 to 1 by 2100.
This year,
daily record highs have been outnumbering record daily lows in the U.S. by a ratio of 9 - to - 1.
During the past week, there have been 576
daily record high temperatures set or tied in the U.S., along with 631 warm overnight - low temperature records set or tied.
As Wunderground recently reported, through July this year, the United States has seen 15,061
daily record highs and just 2,709 record daily lows.
The modeling results indicate that, if nations continue to increase their emissions of greenhouse gases in a «business as usual» scenario, the U.S. ratio of
daily record high to record low temperatures would increase to about 20 - to - 1 by mid-century and 50 - to - 1 by 2100.
Daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows.
In the last decade,
daily record high temperatures outnumbered record lows in the United States two to one, and that ratio is increasing.
This warmth is especially well reflected in a swarm of
daily record highs and record - warm lows at Galveston, TX, where records began in 1874.
A staggering number of
daily record highs have been set in recent days, especially when juxtaposed against the sparse number of record lows this month.
Daily record high temperatures were toppled in many cities on Saturday.
