Mr Data can you post a list of Julys that had both below average C.E.Ts and above average sunshine levels in the same month? Thanks in advance.

Indeed it is reassuring that we can still get below average months without potent Northerlies and cool nights. With a predominating Returning Maritime Polar airmass July 2007 is also part of that short list of cool Zonal Westerly months since January 1984.

I do treat it seriously. I am very worried about the stability of our climate and the world's climate for that matter. I don't deny that global warming is real. I hope that the world stops it before it is to late...

I use the 1960-1991 period because this period looks normal for the C.E.T zone's expected climate "Cool Temperate" because warm and cold extremes were roughly even matched in the 1960-1990 period thus producing roughly normal conditions over this period in the C.E.T zone. However warm extremes have dominated the 1971-2000 period more than anything else thus producing a warm skew in the C.E.T zone towards an unexpected "Mediterranean Climate".

August 2007 C.E.T 20C. This August will be dry and the warmest on record based on the following factors:- 1 "As the nights get longer the heat gets stronger" between June 21nd and August 31st on average due to the seasonal lag between the commencement of shortening days and cooling land and sea temperatures. 2 Runaway Global warming

Indeed the 16 month interval from March 2006 to July 2007 must be the longest interval on record between sub 1960-1991 C.E.T months.

If we don't stop global warming we will get a "winter" in the future that will make the summer of 2003 look like the winter of 1962/1963.

Thats what I do as well.

We won't be getting a cool September this year. According to todays Daily Express were going to be getting a warm August AND September. Oh and the rest of the Autumn will be wet and windy as well. We all now what that means for the winter...

If the final C.E.T for this July is above 16C I will NEVER expect a cold month ever again.

Yeah it would nice to have a sub 1960-1991 month for a change. However what are the odds of the July C.E.T still being below 16.1C by the end of the month?

It looks like Britain just can't win. So a strong La Nina helps mild winter conditions and yet the winter of 2006/2007 had an El Nino.

We haven't had a cold autumn since 1993...

That will be almost impossible. Even the coldest summer months will have seen at least one 20C in the UK.

Even worse. There is something that looks like a weak El Nino signal developing in the Eastern Equatorial Pacific with waters slightly above average near Peru...

If your right this July will be the first below average month since March 2006 in the C.E.T zone at least. :lol: Could it be a Fohn Effect is acting on the Southwesterlies to produce above average temperatures in Northern England and Scotland?

I think it is very likely that September 2007 will be warm. A relentless trend for above average Septembers kicked in 1997 and was only temporarily bucked in 2001 with the unexceptionally cool September 2001. Whilst Septembers 1995 and 1996 were average we haven't had a significantly cool September since 1994 and a very cold one since 1986. September 2006 well... that was just out of this world... 30C will definitely be reached (and breached) numerous times in July, August and September this year. The UK warming just keeps breaking through the ceiling...

Spot on Nick. I also think that Daniel is forgetting the Anthrogenic Enhanced Greenhouse Effect which will at least dramatically offset any Sunspot Minima cooling if not offset it completely...

Just wondering. If June 1975 and June 1791 had only warmed to June 1675 (C.E.T 11.5C) levels after the snowy cold spells - would those Junes have been the coldest on record with a C.E.T below 11C? Incidentally because of the subsequent warm spells following the snowy spells both Junes 1975 and 1791 had the same C.E.Ts of 14.7C.

I fear it will take a global wide reduction in greenhouse gasses and a good couple of centuries patience just to even get close to the 1961-1990 average. This ain't gonna happen the way the world is acting...

It is possible that the Southeasterly was warmed by the anomalously warm North Sea. Hence sea level air temperatures were still above average despite the 6-7C 850hPa temperatures.

I don't like high nighttime temperatures ether. They only benefit those who want to have a party outside at night. I can't sleep very well with muggy nighttime temperatures.

Does anyone know the average 850 HPA temperatures for the period 1960-1991 over Britain for each month of the year? I would like to know so that I can compare potency of Northerlies and Southerlies between the 1960-1991 period and now. Thanks in advance

That must have been one of the rare occasions when a Returning Maritime Polar airmass really felt polar together with late January 1984 and early March 1995.

The Boxing Day 98 Gale was also accompanied by a shallow "heat wave". According to http://www.personal.dundee.ac.uk/~taharley/1998_weather.htm there was a high of 15 C in the Midlands on Boxing Day 1998 eventhough the 850 HPA temperates were below -2C all over of Britain. http://www.wetterzentrale.de/archive/ra/19...00219981226.gif
