Recommended Posts

A bit late but I'll go for a CET estimate of 8.4C a very mild month with a brief cold snap in the second half.

Is that a new entry you want (with the 2 days late penalty) or would you rather stay at 6.6 C and 60 mm as per the earlier entry? Just wondering as I will be making up the tables tomorrow. Not saying you forgot the earlier entry, but it happens (and I get a message later about it) so thought I would check as these changes are fairly small (if you're right, you'll end up scoring just a tad higher after the late penalties).

Thanks as always Roger, interesting to note that we have no -3.x daily records but three -4.x ones (1858, 1904, 2010).

Also Rog and Rel.

Note that it has taken nearly 250years to even reach the levels of warmth recorded in 1772.

We are used to seeing cold records for the 18th century, but this indicates that large changes were also taking place at that time.

Thought I hadn’t posted it, leave it as it is...even though I think higher will score.

An odd thing about the Dalton minimum was that while cold was certainly the dominant feature (winters were every bit as cold as the Maunder minimum), occasionally it got quite warm. These months between 1795 and 1835 show that record warmth was quite possible with the low solar background (I've noticed that the Sun got active around 1837-38 before the climate showed much response perhaps by the next peak in 1848). 

WARMEST MONTHS in the DALTON MINIMUM PERIOD 1795 to 1835 (approx)

JAN _ 7.3 1796 _ tied 2nd warmest, 7.1 1834 _ 4th warmest

FEB _ 6.5 1815 _ tied 19th warmest (1794 was 7.2, 5th warmest)

MAR _ 7.8 1822 _ 17th warmest

APR _ 10.4 1798 _ 4th warmest

MAY _ 15.1 1833 _ warmest

JUN _ 17.3 1826 _ 3rd warmest __ 17.1 1822 _ 4th warmest

JUL _ 18.4 1808 _ tied 9th warmest __ very warm first half July 1826

AUG _ 17.9 1826 _ tied 12th warmest __ summer 1826 was 2nd warmest

SEP _ 15.1 1825 _ tied 19th warmest

OCT _ 12.7 1831 _ 7th warmest

NOV _ 9.5 1818 _ tied 3rd warmest, 9.1 1817 _ 8th warmest

DEC _ 7.4 1828 _ tied 8th warmest

______________________________________

So the Dalton era managed to produce top ten warmest months (to this date) in eight of twelve months. 

It managed a top twenty in every month. 

There's more to these solar minimum periods than just cold. The comparison to the Maunder is interesting. There are several months that don't have a top 30 listing before 1710, the spring and autumn are most warmth-challenged. The only top ten month in the years 1659 to 1709 was June 1676 (18.0, 2nd warmest). Jan 1686 was tied 11th and then Dec 1710 managed a tie for 5th.

Looks a bit like what is happening now if it was this varied.

This is my guess too, lower energy available allowed the atmosphere to play games with the jet stream and it can't be cold everywhere unless the incoming heat energy really drops off as it did apparently from 1670 to 1709 (what's interesting about the 1660s is that the Maunder hadn't really completely set in and you can see it looks a bit like the early 20th century rather than the cold cold patterns later). 

The mid-19th century has more signs of a cold zonal bias indicating that perhaps as energy returned from solar activity increasing, it took decades to restore the balance of more average variations, possibly around the 1870s but then another solar downturn postponed any real warming until after 1920.

Up we go now, how high can we get though? Coldest days might possibly turn out to be the 1st two of the month, or will we get a cold or very cold period towards the end, interesting month this.

Not quite end of the third day yet, but if any further entries after this post, will note them at end of tables of entries which are now posted here:

https://www.netweather.tv/forum/topic/75427-cet-competition-the-scores-ongoing/?page=10

Median forecasts are 6.9 C and 84 mm (slightly cooler and drier than average).

If the jet gets much slacker we`ll get a cold surface SEly flow.

I suspect we will be back at average or above within a few days.

It would be nice to get the coldest autumn of the century for a change but for that we need to beat autumn 2010s 9.77C and for that, November 2018 must finish no warmer than 5C.
