asked the Secretary of State for Air if he will give an explanation of the incorrect weather forecasts given by his Department during the recent cold spell.

To my regret I must admit that the science of meteorology still leaves much to be desired. During the recent cold weather, however, the Meteorological Office issued about 2,000 weather forecasts for the different regions of the British Isles and of the surrounding seas, and many thousands to the crews of British and other aircraft, and I am advised that the vast Majority of them were correct. I am placing copies of these recent forecasts, and of the subsequent weather reports, in the Library of the House. If the hon. Member finds among them any to which he takes particular objection, perhaps he will put down a further Question.

Is the Secretary of State aware that the Air Ministry predicted two thaws which did not come off, and that once they predicted rain and fog, which, fortunately, did not arrive? Will he try to improve the reliability of his forecasts, in view of the great inconvenience this country has suffered from the unreliable forecasts of the Minister of Fuel and Power?

I am aware that, as someone said, one "thawcast was a frost." I am also aware that many people tend to confuse the science and the practitioners of the science. The science is imperfect, but I think our practitioners in the very difficult conditions of the British Isles really do remarkably well.

Is the right hon. Gentleman's difficulty that the information which is available will take, at least, six months to collate, and that, like so many other Government plans, that is quite impracticable?

That is not at all the case. So valuable is the information that a number of commercial people want to pay us money to obtain it.
