Book excerpt: Malcolm Walker tells the story of the UK's national meteorological service from its formation in 1854 with a staff of four to its present position as a scientific and technological institution of national and international importance with a staff of nearly two thousand. The Met Office has long been at the forefront of research into atmospheric science and technology and is second to none in providing weather services to the general public and a wide range of customers around the world. The history of the Met Office is therefore largely a history of the development of international weather prediction research in general. In the modern era it is also at the forefront of the modelling of climate change. This volume will be of great interest to meteorologists, atmospheric scientists and historians of science, as well as amateur meteorologists and anyone interested generally in weather prediction.
