Here’s a term we hear from time to time on the weather forecast. But what does it mean? Cyclonic conditions are usually found in the centre of a low pressure system away from any fronts. The pressure is fairly static and is as low as it’s going to get. There often isn’t a great deal of wind, although there may be, but one thing is sure, no forecaster can tell us what its direction will be because there are no isobars to define it. The sea is likely to be somewhat confused as well if the low is vigorous, so if the forecast says cyclonic, things could be worse. There’s only one problem. If the system moves, to get you back into the isobars, it’s likely to breeze up pdq.
