May weather extremes
« on: May 08, 2020, 07:07:15 AM »
One interesting thing the news hasnt covered much yet is all the talk among the climate scientists.  Since the pandemic started, global temperatures have been dropping at record pace.  This wasnt supposed to happen as CO2 levels in the air are still at near record highs.  None of the UN models can explain this.  It suggests another contributor.  One hypothesis is that it isnt CO2 but rather plane exhaust coverage that is causing greenhouse effect. Regardless, it is creating a lot of excitement aa people wait to see if the trend towards lower temps continue.

Man it's cold out there.  Locally we are forecast to break the record low temperature today which was last set in 1945.  It will also be the latest freeze day in recorded history.  People are rushing to cover gardens. Really bad part is we have to fill homeless shelter potentially exacerbating infections among that vulnerable group.

Any other TSP'ers in the freeze zone today?

Yeah but it's not outside normal for us. Our "put the garden in" over/under is Mother's Day. If it's a little later this year that's not a big shock.

we have been in a heat wave -- too hot to plant the corn -- we are hoping for it to reduce towards normal temps this weekend.  The heat makes my allergies that much worse, it has been debilitating this week, worse than ever, and I realy, realy want to finish up bed prep as ALL the summer starts need to go out  -- I have an extra large garden going this year.  Soon the spring potatoes will be ready to harvest, a bumper crop

Quit hogging the warmth and send some of that our way!  ;)


They are now forecasting record low temps in central New York along with late snow.  Been a very long time since May snow has been seen in a lot of these areas.

I am used to frosts here in May.  I am not used to snow in May.  We may get some tonight.  The only thing that bothers me about all this cold and snow is my fruit trees are starting to bloom.  Everything else can handle anything but a hard freeze. Even if we get a hard freeze I have a second round of planting to replace all the stuff I set out early this year.

Our typical last freeze is April 16, but it is forecast to get down to 32 here tonight... I do have my tomatoes out already, so I'm going to cover them just in case. I'm waiting until this chilly few days is past to plant the peppers.

Many in Australia are calling it surreal.  They jumped from record highs to record lows.

Woah.  It was cold this morning!  Records broken all over the US.  New York City even had unforcasted snow in Central Park. 

https://weather.com/safety/winter/news/2020-05-09-new-york-city-record-latest-snowfall
New York City Tied Its Record Latest Spring Snowfall, In One of Its Least Snowy Seasons

Snow fell in New York City early Saturday morning, tying the city's record for the latest snowfall in spring.

Just after 1 a.m. ET, a chilly light rain transitioned to light snow at New York City's Central Park. The snow persisted only for about half an hour before ending as sleet just before 2 a.m.

While the snow didn't accumulate, it tied the record latest date in spring of snow documented in Central Park, dating back to 1869, with May 9, 1977.


To put the temperature drop in perspective, if this continues for two more months, the global temperature will be below the 30 year (1981 to 2010) year baseline.  In other words, the last decade of temperature increase will have been reversed in a matter of few months.  Unfortunately, this isnt what we need to kill off COVID-19.

We're in 6a but didn't get the expected 36 temp and possible frost last night. Our heavy frost was about 3 weeks ago.
Still, we could possibly get frost tonight, but I have all above ground plants covered with water jugs.

I woke up to snow this morning.  We didn't get above 41 degrees today and we had 22 mph winds to go with the snow.

Sort of, but not really.  Maryland had record low temperatures last night.  Beat the low temperature by 1 degree F.  Still above freezing, but dang it's cold.  High temperature today was about 45, but felt like it was 34.

Tonight, we are going below freezing.

Severe Weather Europe have reported a "marked cold snap" is expected over the days of May 11 to 13. The northern parts of the continent are set to face an "intense Arctic outbreak". The foreseen pattern will bring "significantly colder air mass" across many countries.

Freezing temperatures in Europe around middle of may aren't that unusual, there is even a centuries old name for it around here, translates to ice saints. Another cold period is common in june with a temperature drop of 9-18°F.

The continuous heat we had the last two years was much more unusual and problematic due to the parallel dry weather.

What is unusual and unexpected is the rate of this drop in temperature. It is enormous.

The coronavirus is giving us an unprecedented global scale experiment.  Up till now, the climate models have been based on completely untested assumptions; one of which is that warming trend is almost entirely driven by CO2 level in the air and cloud formation, aerosol levels, etc play little if any role.  With the coronavirus reducing activity, this is giving a test of these assumptions.  If the CO2 hypothesis is correct, then there should be no change in global temperature given this reduction in activity as CO2 in atmosphere (it is assumed) takes decades to dissipate.  Instead we are seeing a drastic drop in global temperature giving extremely low chance this drop is just random fluctuation.  We will have a firm answer if trend starts to rebound as activity picks up. 

So, the experiment which was originally seen as simply enabling a better understanding of sources of emissions is instead, at first look, challenging what we thought was known

Coronavirus has created conditions for unique environmental science 'global experiment'

Stay-at-home orders enacted to slow human movement, and consequently the spread of COVID-19, have had obvious benefits for the environment, but they are also impacting environmental science. Researchers are racing to collect atmospheric and other data, which they can use to assess their climate models and determine the extent of the impact of the coronavirus on the environment and human health as it relates to pollution and air quality.
...
There's a global experiment going on in our atmosphere," said Joellen Russell, professor in the University of Arizona Department of Geosciences.
...
Carbon dioxide and methane, two of the most potent gases that contribute to global warming, are not very reactive and linger in the atmosphere, making it challenging to disentangle the new gases from what has been there for decades.
...
"The scientific opportunity here is that there are currently some large and well-known changes in human activity. That offers a known input to better disentangle what's contributing to gases in the atmosphere."

Colder than Christmas! Scotland suffers one of the coldest May days for 23 years thanks to 1,000-mile wide Polar Vortex with minus 5C freeze on way tonight

Scotland has suffered one of the coldest May days for 23 years thanks to a 1,000-mile wide Polar Vortex with a 5C freeze on its way tonight. 

Snow flurries are forecast overnight on Scotland's hills with the mercury plummeting to -5C, as out-of-season frost kills garden plants.

Highs of 7C to 11C, 5C below average, will feel even colder in bitter windchill tomorrow, with the chill easing from Friday as temperatures rise to 15C by the weekend.

Boy that was crazy one for the books.  Some are postulating more record colds were hit over the week than ever in modern reporting. Rare to see plummeting temperatures both in North and South hemispheres.

Nearing the end of June and so far we have had only several hot days. 59f now seems awfully chilly, and overcast, rain.

Several too warm of the days here in Missouri for June also.
And like you say, 60 seems cold.
