Extra info for 50 Ways to Improve Your Weather Forecasting
This air coming in from seaward is the sea breeze – hence its name – but the rising warm air over the land will cool as it rises and in doing so it tends to flow out to sea and drop. Eventually, once the sea breeze becomes fully established, a circular airflow is created, with cooler upper air flowing out to seaward to replace the air being sucked in by the rising warm air over the land. This circuit of warming and cooling is a small, self-contained weather system in its own right and it usually starts up after midday when the land has warmed up considerably.
Now, the sea area that is covered by the forecast may be quite considerable, covering an area extending perhaps for 500-650km (300-400 miles). If the weather is moving through that sea area, your position within the area will have a considerable bearing on when that ‘later’ period occurs. Weather patterns may move at speeds of anywhere between, say, 10 and 40 knots, so it will take on average perhaps 10 hours for a forecast change to move through your particular sea area. It could be longer, it could be less, but if you have an understanding of the weather patterns you should have some idea of the speed of change.
An area where the distance between the isobars is less could later become an area where the isobars are closer together, suggesting that the wind will increase in strength during the forecast period. If you have consecutive weather charts available, you’ll be able to get a good picture of when and how the wind strengths will change. It is when you are having to rely on verbal or text weather information, such as that given over the radio, that you will need to interpret the forecast to get a better and more reliable idea of how the wind strength will develop and change.
