Summary: THE Weekly Weather Report of the Meteorological Office, Air Ministry, for the period February 28,1932-February 25, 1933, in the British Isles, is the fifth of a new series that began with vol. 45, published in 1929; the introduction to that volume explained the changes introduced in the new series. The week is commonly regarded as the unit of time best suited to the needs of agricultural meteorology, and this report is designed in other respects with the same needs in mind for example, ‘accumulated temperature’, which is calculated with 42° F. as base, above which many forms of plant begin to grow, and statistics of’ ground frosts, that is, frosts registered by a thermo meter set on the grass and freely exposed to the sky as are the upper surfaces of the leaves of the top most sprays of plants, are among the items included. The tables are set out in such a way that the whole year's succession of weekly data for a single station occupy one page. There are 57 stations, well distri buted throughout the British Isles; these are also grouped into twelve so-called ‘districts’, and the deviations of the various meteorological elements, temperature, rainfall and sunshine, from normal values of these elements for a long period (generally 1881 1915) are averaged so as to give ‘district values’. The district values are set out for individual weeks, and these are grouped into the four seasons, for each of which there is an appropriate seasonal mean deviation from normal. The season under review was one of generally deficient sunshine with more than the usual rainfall. The data for the Midlands and for the eastern districts of England and Scotland would be suitable in a study of the agri cultural results of a wet spring, as that season was notably wet in those districts.
