  1. How Meteorology became part of the Royal Navy: Part One

    Despite the fact that we are an island race who have been reliant upon ships to leave these shores from time immemorial and, more importantly, have needed ships and some sort of navy to repel the invading hoards; meteorology and the Royal Navy have been seriously linked together for less than two hundred years. In fact the RN has had its own meteorological branch for just short of one hundred years. Through a series of articles it is hoped to reveal some of this fascinating history for the very first time.


    For many years weather was recorded in the Captain's log book every day the individual ship was at sea. This was not just military ships but merchantmen as well. Where did the knowledge come from and what was the training? The answer is simple, the only training was a lifetime’s experience of being at sea and building up the ability to recognise certain signs and situations and the effect they had upon the ensuing weather. Instruments for reading,

  2. Autumn in the Garden

    October is when we see the nights draw in rapidly and daylight quickly diminishes. So if you have a garden -and more importantly the time!- time to start on the autumn chores, gather up all the garden waste and have a bonfire. Although its not considered especially ecologically sound anymore to have them,  I have to admit to still getting very nostalgic about the tradition, something about the smell of woodsmoke in the autumn drifting through the countryside seems quintessentially 'English' (and quite possibly Irish, Welsh & Scottish too, if you are from those areas!) .

    As I mentioned though, local councils do encourage gardeners to reduce waste by composting as much of the refuse as possible especially plants waste. You can buy compost bins from your local Community Recycling Centre if you wish to keep it a little tidier. (look at your local council website or phone up to see what is available; some will even deliver them to you free of charge)

    If you decide to go ahead

  3. Accuracy of Weather Instruments

    The High-Accuracy Davis Vantage Pro2 Weather Station

    The accuracy of weather instruments we offer varies from very basic up to scientifically accepted. Generally the level of accuracy is reflected in the price. Bear in mind that it is often trend or linearity that is more important than accuracy.


    Digital consumer products often state resolution which should not be confused with accuracy. Resolution is simply the number of decimal places that the instrument can display and not its accuracy. Consider also a traditional bulb thermometer where the accuracy depends on the scale being correct and aligned correctly as well as your ability to read off the mensicus against that scale.

  4. October Garden Tips

    By October it's time to start tidying up the garden in preparation for the long relatively sunless and perhaps wet winter period ahead. Jobs can be divided into those that tidy up the garden after summer, those that allow it to hibernate over the winter period and jobs which prepare it for the coming spring and summer.


    For autumn:

    You'll need to split and divide herbaceous plants whilst weeding and mulching the border. Remember to remove diseased plants (or parts of plants) so they cannot propagate any further or spread the infection to other healthy plants. Winter is a prime time for this to occur. You'll need to check bushes and trees for stability, especially those that have grown a lot during the last summer and prop them up or re-stake

  6. Understanding the Weather Map

    One of the most important things anyone wanting to understand the weather can learn is how to recognise the salient features shown on a weather map.

    The first thing a meteorologist will draw up on his or her chart (although nowadays nearly all maps are generated automatically by computers) are lines of equal pressure from observations. These are usually in millibars (mb) or sometimes inches.

    We call lines joining points of equal pressure isobars. They are helpful because by creating them we can start to identify areas of high and low pressure at both the surface and aloft, that control our weather pattern. Pressure values are generally corrected to Mean Sea Level Pressure (MSLP) so that a standardised level can be shown, otherwise the observers height would affect the readings, as pressure decreases with altitude quite substantially.


    The chart below shows a map with pressure readings taken from

  7. Weather Forecasting at Sea

    Last month we talked about some of the ways to get forecast weather information of specific use to the marine community. As I mentioned then though, if you know your met well enough then you'll be able to supplement the forecast with information on the hoof, interpreting changes to the weather as you go along.


    What then are some of the signs that can warn you in advance of the imminent development of stormy weather, that for smaller craft and crew can cause the most problems?

    Generally, sea and swell will take their time to rise and you can usually be aware of these changes enough in advance to head for port. However the most rapid changes usually occur when atmospheric conditions cause sudden squalls and thunderstorms. These are often linked to frontal passages and again, a quick check on the forecast weather chart will usually show if you are likely to encounter them on your journey. A cold front in particular will often give squalls and heavy

  9. Dealing with Damp Summer Weather in the Garden

    The main problems associated with damp gardens in the summer often hinge on the flora being too close, so you need to ensure that areas of denser foilage are well ventilated. In the summer garden you do need to catch disease as soon as you spot it, as it can take hold surprisingly rapidly in a relatively warm damp environment.

    Particular diseases to look out for, in warm damp summer weather, include rose blackspot (small dark spots appear on the leaves which may turn yellow and fall off as spores are carried in water splashes); firelight, unusual but it attacks pear trees, hawthorne and cotoneaster and apples and pyracantha. Branches wilt and the leaves turn a burnt chestnut colour, spreading down the main trunk until the whole tree looks burnt. It is mainly carried by pollinating  insects and by raindrops between June and September.

    Downy mildew is a late spring/early summer fungal disease that appears as an off white rather 'fluffy' growth underneath

  10. The Christmas Blizzards of 1927

    The so called 'Christmas Blizzard' of 1927 was one of the worst blizzards of the 20th century to hit the southern UK.On Christmas Eve, there was a cold ENE'ly flow across the UK bringing with it snow showers to the east coast and night frosts.


    By Christmas Day, a low pressure had moved into the English Channel of around 987mb and this then engaged the colder air to the north and east. Initially, the precipitation that fell was rain but as the low pulled down even colder air from above, the rain turned readily to snow and by midnight, many southern and southeastern counties had a snow cover. Conditions the next day were very bad with heavy snowfalls and a gale force northeasterly wind bringing blizzard conditions and severe drifting. Villages were cut off by drifts up to 6-7 metres (20 feet) and food supplies had to be air-dropped. Transport was virtually paralysed with train services seriously delayed or cancelled. Even in central London, depths of snow
