Shock horror, a cool showery April for a change

Tony:

No, you did not imagine it, it has been miserable for far too long so I haven’t ventured out much. This is partly the reason for my lack of posts, alongside a busier working life. More news to come, honest!

These are early figures covering 1 – 25 of April and not full month statistics, so are therefore very likely to change. Especially regarding ranking. Full month figures will not be available until provisionally Wednesday 2 May.

Figures for 1 – 25 April show the month so far has seen well above average rainfall across the UK, with 97 mm of rain recorded – this is 139% of the long-term monthly average (1971-2000). The wettest April in the records dating back to 1910 was 2000 which saw 120.3 mm of rain.

Currently the month is the 9th wettest April for the UK in the records. However, it’s not possible to say where the month will end up in the records until all the figures are in at the end of the month – especially as we are expecting heavy rain on Sunday.

Some areas have seen significant rainfall amounts with some parts of the…

Full Moon Phenology

The first Spring Full Moon (meteorologically speaking) has been and gone and our distant planet is on the wane once more. I have found it intriguing over the years how the moon phases, more especially the Full Moon, alter the flora and fauna around us. Maybe it is my overactive imagination but with the lengthening of daylight also increasing, are there not observable changes? Let us recap the first ten days of March, phenologically speaking.

On the 2nd March I first observed the emergence of leafing Elder (Sambucus), the mean date of this event returning 4th March, based on twelve records. Come the 3rd March my brother confirmed a Thunder day (Thunder heard or lightning seen). Personally, I was away at a B.T.O conference so could not confirm this event. The very first Thunder day, based on sixteen records also returns a mean date of 4th March. Weather wise, the 4th March was a wet day, hoorah! Of the 12.6mm, which fell during that day, a small proportion was actually melted wet snow. Between the 5th and 7th March, things calmed down once again until the arrival of the Full Moon 8th March.

A Siskin (Carduelis spinus) visited our garden feeders for the first time in ages, although if you are lucky they may be heard calling in the vicinity. On this day (8th March), the raptors were very noticeable with two Common Buzzards (Buteo buteo) and two Red Kites (Milvus milvus) circling above our suburban patch. A Sparrowhawk (Accipiter nisus) visiting us on the very next day. The phenological indicators were not overlooked with the following being witnessed. The first emergence of Flowering Coltsfoot (Tussilago farfara), Flowering Wild Daffodil (Narcissus pseudonarcissus) and the first leafing of Hawthorn (Crataegus) all observed during the busy 8th March.  Looking closely once again at the dates of average occurrence of these events, they return the 5th March, 9th March and 12th March respectively.

Breaking news for today (1oth March) has been my first garden Frogspawn and first emergence of Brimstone Butterfly (Gonepteryx rhamni). Once again when looking at the averages, the returns are the 9th March and 12th March, both being based on a healthy sample of records.

As to the future, many more phenological events will be likely as warmer weather is in the forecast. In fact, even as I type this, the warmest day of the year is happening with the Air Temperatures approaching the mid-60’s Fahrenheit. Oh how I love this time of year!

“All eyes to the South” once the snow clears

Today has been a mix of wet snowflakes and cold sleety rain. Temperatures, which had been falling earlier, are now on the rise, so I am somewhat glad to be indoors.

Now that the official winter climate statistics are in, it is time to have a look back at how the season fared. This is achievable courtesy of this link – here. My figures tie in nicely with the actual C.E.T. Temperatures, with my anomaly being approximately 0.6C above average. The rainfall figures continue to show their undeniably downward trend, with a deficit of 43mm or so. According to my figures, we have received only 73% of the average precipitation across the winter season with 82% officially reported for England as a whole. After the warmth and dryness of autumn, I do hope spring brings us much-needed rainfall. With plans locally for yet more urban development (many thousands of new houses), our natural ecosystems will face damage beyond recognition. 

On a lighter note, the spring equinox, is approaching fast and migrant birds are on the move. I like to track this phenomenon online and there are many ways to do so. A website that I would highly recommend is The Gibraltar Ornithological and Natural History Society. The aforementioned website can be an excellent resource for tracking the incoming and outgoing African migrants due to its global position. In addition, from a UK perspective, I use reports from birdguides and it is from here, that I will quote a few recent highlights.

Barn Swallows (Hirundo rustica) have possibly overwintered in the UK once again, with more recent coming from Cork and East Sussex.

Sand Martins (Riparia riparia) are being quite widely reported in low numbers. Yorkshire, Norfolk, Bedfordshire, Manchester and Pembrokeshire, has reported this species so far.

Reports of Stone-curlews (Burhinus oedicnemus) received from Devon and West Sussex and a Hoopoe (Upupa epops) from Nottinghamshire are interesting. I am also aware of two reports of Ospreys (Pandion haliaetus), one being in January from West Yorkshire and a February sighting from Gloucestershire.

I suspect there are other tales of interesting sightings and it shows the build up to migration changeover is gathering pace.

Best Wishes

A wintry weekend in store

Tony:

So the UK’s winter is finally set to bite. Will I be getting snow or cold rain, come the weekend? Some answers to this being above, courtesy of the professionals.

This weekend will see a marked change in the weather as the dry spell makes way for snow and ice in many parts.

Over the past few days we have seen the coldest spell of winter so far, as very cold air has flooded across the UK from the continent. Temperatures have dropped as low as -9.4 °C in Shap, Cumbria, and -10 °C is possible in places tonight.

Snow showers are expected along parts of the eastern coastline today and tomorrow, but most places will continue to see bright, dry and cold conditions.

Things are set to change as we go through into Saturday, however, as an Atlantic front moves in from the west.

Paul Gundersen, Chief Forecaster at the Met Office, said: “As this front moves in from the west it will come up against cold air and we’re likely to see a mixture of rain, sleet and…

Hello winter.

Welcome to winter, well only in terms of the meteorological calendar, is it winter. Confused, see the winter solstice pages here.

So on reflection, what was meteorological Autumn like, well when looking back at my weather station, you can clearly see the UK (at least the southern part) was both, exceptionally mild and dry. The figures in the red boxes show consecutively warmer months, with November notably warmer than average. The figures in the blue boxes show the worrying rainfall deficit, each month, being well below normal.

Looking back at Autumn
Looking back at Autumn

Actually, if December was to become even a normal month, in terms of precipitation, i.e. with 64.7mm falling from the skies from this point on. The deficit would still be, well over 100mm (4 inches) in old money. It would be depressing times indeed, if this were to continue, furthermore the official forecasts I’ve seen, suggest it will. Into 2012 and beyond, there is likely to be a desperate need for water in Southern England, because bizarrely, the current government wishes to reinvigorate our economy, by creating yet more urban development. This part of the country is already under strain in terms of its population, a crude estimate of 25 million, with 12-14 million in the London area alone. Sadly, in my opinion, the first thing requiring reinvigorating is the rainfall. Statistically, the trend of decreasing rainfall down south has been continuing for many a recent year. However, much further north, the reality is most certainly different.

This is most definitely, a cause for debate.
