Ground water levels in drought hit East Yorkshire now normal

Paul Hudson |16:03 UK time, Thursday, 10 May 2012

Record rainfall in April and a wet start to May has improved East Yorkshire's ground water levels to such an extent that Yorkshire Water has today announced that they are now back to normal for the time of the year.

This is a remarkable turnaround considering stocks were 20% depleted only 6 weeks ago.

With more rainfall forecast during the rest of May, pressure will mount on the Environment Agency to lift the drought order that currently affects the county.

Droughts have a history of ending far quicker than experts anticipate.

Back in the summer of 1976, experts talked about endless months of rain being needed to restore ground water levels, and that the situation may take many years to fully get back to normal.

Despite the Met Office in August 1976 forecasting a 'dry September, with no clear indications of a wet autumn anywhere', September and October were extremely wet that year, so much so, that by the end of October, soil moisture deficits were normal, and by November, most bore holes were at or above average.

In the end the famous drought of 1976 was over far quicker than anyone anticipated.

And from a forecasting point of view, history seems to be repeating itself.

The Met Office seasonal forecast issued in March, and seen by the Environment Agency at the time, stated that April, May and June would see a continuation of the dry weather, with April being the driest of the 3 months.

Moreover, the Met Office said that there was only a 10-15% chance of seeing the heavy rainfall that we experienced in April, which turned out to be the wettest on record.

One main difference with 1976 is that peak evaporation occurs in June, July and August, and rainfall, should it occur in these months, would have to be heavy for it to outweigh moisture which is lost through evaporation, and the moisture taken by plants and vegetation.

In 1976, heavy rainfall fell through autumn, a time when evaporation rates fall sharply, leaving much more of the rain to replenish stocks.

According to Anglian Water, groundwater levels in Lincolnshire have recovered, but they are starting from a much lower position than those in East Yorkshire, and so remain depleted and will take longer to get back to normal.

Nonetheless the fact that East Yorkshire's groundwater levels have now returned to normal shows that once long dry periods come to an end, the prolonged heavy rain that follows can improve the situation quicker than anyone expects, like in 1976.

    Paul - the way May is going April may be the driest of the three months.

    Wow yet another record broken



    The shortest drought in all recorded history!

    HI PAUL

    IT THAT WET ON OUR ALLOTMENT IN WORKSOP, WE HAVE DUCK SWIMMING IN THE POOLS.

    IT IS SO WET WE ARE UNABLE TO PLANT POTATOES AND SOW SEEDS.

    Coincidentally, I saw a duck wandering around one of the local supermarkets today, possibly attracted to the large puddles of water which were about.

    It seems that if there is a drought, all the MO have to do is forecast dry weather and the problem is solved!

    Anyone know why the NDSC NH data on Cryosphere Today seems to have 'frozen' since the 4th? (strictly no pun intended)

    From my vantage point it stretched from horizon to horizon in the midlands moving from south west to north east, absolutely fabulous sight to behold.

    It might have been something to do with the division between cloudy/rainy weather in the North and finer weather in the South, but unfortunately I don't have a weather map for the appropriate time.

    The Sea Ice extent got close to the average, but lets be honest it would have to cross it and stay there for years to have any effect on the average. It's now back well below.

  • Comment number 18.

    Seeing as those oh so infallible scientific types were telling us that it would be ice free round about now, then the 'average' spell was nothing short of miraculous

    That's possibly due to the fact that it isn't really getting any warmer in the Antarctic.

    Regarding the East Yorks drought:



    The springs which have been dry for so long here are now running again more or less as normal. So groundwater levels must be right up, as PH says. On the whole I think that plenty of rain at this time of year is a good thing. Vegetation and crops are growing well.



    We could do with a bit of warmth though. It seems to have been on the cold side for weeks now, though mercifully the severe frost expected last WE did not materialise. Yesterday I believe, an amazing 21c was recorded at Leconfield but this has been very much the exception. East Yorks was just inside the warm SW wind belt that covered southern Britain and we had a rather pleasant afternoon. This has already gone and been replaced by chilly polar air again.



    Swifts and swallows have been late but have finally arrived in good numbers.

    "the 'average' spell was nothing short of miraculous"



    If cryosphere today was still up I could show how 'average' is reached once a year most years, including the last few. I think there was only one year that average didn't happen at some point.



    It used to be the case of course that it was very unusual to get below average, now it's a big event when we almost touch it.

  • Comment number 23.

    whoops stupid me CT is up of course, it's just frozen, so what I meant was this:

    https://arctic.atmos.uiuc.edu/cryosphere/IMAGES/sea.ice.anomaly.timeseries.jpg



    almost every year hits the average line, or gets very close to it. There's more than one that didn't. In terms of ice free, it's the lower trough parts of the graph that are more interesting.



    In the above graph if you start at the beginning you notice each year the ice stays within a single box. In the early 80s the ice sticks in the box spanning 0 and 1mil sqkm. Ice very rarely dips below that 0 line. As we hit the 90s we see ice going below that line more commonly, in fact it seems the ice is hugging the 0 line. In 1995 is the first year in which the ice drops into the 0 to -1 mil sqlm box. By the early 2000s that's become the pattern each year. By 2006 it seems to be dropping towards the next box, then some really weird stuff happens. Notice that since 2007 the ice has started to largely occupy 2 vertical boxes each year rather than 1.

    Just remember you who believe in man made global warming. The water stocks were replenished very quickly. At some stage we will get a lot of cold weather to compensate. But then again we haven't had a decent summer since 2006 and that finished prematurely.

  • Comment number 26.

    It is interesting that AQUA CH5-8 temperatures have now been falling for about 5-11 days, with those at a higher altitude falling for longer. Since temperatures normally rise at this time of year, the daily ch5 anomaly has actually been falling for about 6 days, and the equivalent UAH anomaly is now approximately back to where it was on April 24th. The estimated UAH anomaly is now below what it was at the start of May, and the estimated RSS and HadCRUT3 anomalies are about the same as at the end of April. So it seems that for the time being at least, the recent increase in global temperatures may be slowing down.

    greensand,

    From your link to the Bob Tisdale blog on April SSTs, Tisdale says:

    "With the ebbing of the 2011/12 La Niña, the Monthly NINO3.4 SST Anomaly rose as one would expect in April 2012 (about 0.167 deg C) to -0.30 deg C.

    In response, Global Sea Surface Temperature anomalies have also increased. Both Hemispheres warmed. The only ocean basins to show cooling in April 2012 were the South Atlantic, North Pacific, and Arctic Ocean. The monthly Global Sea Surface Temperature anomalies are presently at +0.134 deg C."

    What puzzles me is the mechanisim whereby the global, and in particular the North Atlantic SST "responds" to a rise in the NINO3.4 SST, since the latter is in the Pacific, and as far as I know, there is no connection between the ocean currents in the Pacific and the North Atlantic. Surely any change in the N. Atlantic SST must be completely separate from ENSO.

    "we haven't had a decent summer since 2006 and that finished prematurely."



    2006 was an unusually hot summer in June and July. June was about 2C warmer than average and July about 3C warmer, then in August temperatures returned to average. https://www.metoffice.gov.uk/climate/uk/anomalygraphs/



    If you skim through the years you can see various times there are 2C/3C warmer than average months. For example last year this happened in February, April, October and November. Warm temperature records were broken during those periods, so this is about as hot as it gets.



    What needs to happen for a scorching absolute temperature is for one of these 2C/3C period to happen during a summer month, which is a matter of luck, although I am sure the odds will be much increased in a warmer world.

    QV @ 27

    I stumbled across this nsidc icelights page a couple of days ago which may be helpful.



    https://nsidc.org/icelights/2012/02/02/the-arctic-oscillation-winter-storms-and-sea-ice/



    If the link doesn't work (my last one didn't), go to the icelights page and scroll down to Arctic Oscillation and click read more.



    It very briefly describes how the AO influences weather in the NH and how it is interconnected to ENSO, trade winds and the position of the jet stream. This may not seem directly relevant to your question, but it strikes me that anything that influences cloud cover will inevitably affect insolation. In this way, perhaps the changes in the pacific can have a knock on effect with North Atlantic ssts.



    To be honest, it all seems so interconnected that I'm surprised anyone can make sense of it. It may also help with your earlier query regarding the up and down nature of arctic temps.

    "Notice that since 2007 the ice has started to largely occupy 2 vertical boxes each year rather than 1."



    Presumably this is due to the large drop in multi year ice? I read somewhere that even second year ice is much harder to melt than single year, and because of this, sea ice extent is now more sensitive to short term weather variations.

    That would be my initial thought QV and as such we are back to the "short-term"

    effect of ENSO. Not difficult to understand a predominance of El Nino's eventually giving rise to increased global SSTs but a move in Nino 3.4 over a few months? Don't fit easy with me.



    I have just seen the following and only had time to skim (and sorry have to admit that is all I have managed with your last few posts but hopefully will get free shortly):-



    "Tisdale: An Unsent Memo to James Hansen"



    https://wattsupwiththat.com/2012/05/12/tisdale-an-unsent-memo-to-james-hansen/



    Lot in there but this caught my eye:-



    "As a result, the climate models exclude the variations in the rates at which the tropical Pacific Ocean releases naturally created heat to the atmosphere and redistributes it within the oceans, and those climate models also exclude the varying rate at which ENSO is responsible through teleconnections for the warming in areas remote to the tropical Pacific."



    The "teleconnections" made me twitch but a quick google of "ENSO Teleconnections" surprised me, not unusual, lots to learn!



    https://oceanworld.tamu.edu/resources/oceanography-book/teleconnections.htm



    At first glance quite interesting, but cannot see an immediate answer re North Atlantic, will get back later, it is growing season and the “drought” has resulted in it being too wet to do a lot of jobs!

    They are in the public domain for all to scrutinise and either accept or reject. And make no mistake they will be!

    Vincent says: I’ve got one problem with ascribing temperature to ENSO – is it the cause or the effect? Does ENSO drive the temperature or does the temperature drive ENSO?”



    Global surface temperatures respond to ENSO. There’s a 3- to 6-month lag between an El Nino event and the response of global surface temperatures to the event.



    A little shorter time frame than I thought.

    Thanks for that.

    I must admit, I can't see it as a cylinder, but it might be a cloud resulting from a front of some sort. I will try and see if I can get a look at a weather chart for the day/time, to see if anything coincides with it.

    Someone else might have more idea.

    "Confused? I am"



    What's confusing is your conflating of conditions 'out your window' with conditions globally.



    April 2012 was the fourth warmest April on record globally according to all the monthly data bases so far released (RSS and UAH satellite, and NASA surface stn data). May is so far looking above average globally according to daily global AMSU satellite data. SST ENSO region 3.4 is now in positive territory, up to +0.14C above average last week and it appears to be rising quite steadily. This normally has the knock-on warming effect of warming global temperatures.



    It may be raining and cold in Knowle West, East Kilbride, and Hemel Hempstead, etc but that doesn't necessarily always have an overriding impact on global average surface temperatures.

    I have been looking at the mean monthly temperature anomalies for the N.H., using RSS data.

    Apart from the N.Polar region, i.e. 60 to 82.5 deg. the mean anomaly peaks in April & September, with the peak in April being higher than that in Sept. and are at their lowest in June and December.

    However in the case of the N.Polar region, the peaks are in April and December, with low points in February and July. On average, the December peak is higher than that in April.

    After September, the other regions anomalies tend to fall, whereas the N.Pole anomalies tend to rise until December, then fall.

    Any ideas why the N.Pole would behave differently to the rest of the N.H.?

    The latest NCDC/NOAA Global State of the Climate report is quoting the following Land/Ocean temperature anomalies:

    Global = 0.65c, compared to the previous March figure of 0.456c

    N.H. = 0.89c, compared to the previous March figure of 0.519c

    S.H. = 0.42c, compared to the previous March figure of 0.398c

    After adjustment to the HadCRUT3 1961-90 base line, the above figures are equivalent to 0.512c, 0.80c and 0.24c respectively.

    According to ncdc/noaa, the global anomaly figure is the 5th warmest April on record, the N.H. anomaly is the 1st warmest April, and the S.H. anomaly is the 16th warmest April.

    The main influence gobally and in the N.H. seem to have been land temperatures, and in the S.H., ocean temperatures.

    The increase in the global ncdc/noaa anomaly is similar to that in UAH and RSS, and points to a HadCRUT3 anomaly of around 0.5c, compared to a figure of 0.46c (+/- 0.1c), based entirely on AQUA CH5.

    The increases in all of the N.H. anomalies so far published are similar and point to a HadCRUT3 anomaly of around 0.72c.

    The increase in the S.H. anomaly is lower than UAH and RSS, but higher than for GISS, which was actually negative. A similar increase in HadCRUT3 would result in an anomaly of around 0.27c.

    I am still awaiting the publication of the HadSST2 figures, which might produce a more reliable estimate of HadCRUT3.

    Confirmation, if it were needed, that the "impression" gained from recent U.K. temperatures is misleading.

    However, as I mentioned in my previous post, N.H. anomalies tend to peak in April, so if that pattern is followed, we can expect a fall over the next few months.
