WEATHER PREDICTIONS.

. OLD AND, NEW METHODS. ■ The Lecturer on Meteorology,- ; Rome • ■ University, '•■ writing in ■ the International; . Review of Agriculture, traces, the history ; ; of the attempts which have been made' to find a clue to weather prediction, and conv cludes with: the statement that the present system employed is radically different from the old method based essentially on statistical data. He ; points out that it f rests upon a knowledge of . the contemporaneous distribution of meteorological factors over a large surface of the globe, for it has ; been ■ ascertained that a compensation exists between the climatic variations of one region arid those of somewhat distant}' parts' of the V; world. Comparative climatology, :" he 4 says, * and - the present dynamics of climates can certainly reveal the first signs of the. successive variations that now manifest themselves to us in a • more* visible manner in the displacement of the great masses of ice - forming. > the. polar ice-caps. Hence, an increase in the network of meteorological posts of observation in the ; ; northern regions ; would enable ub better * to follow the ecntres of - activity : - and ;-to • reveal the cycles in which they occur,, which certainly vary'from one 'region to another. This would undoubtedly bring us nearer to our goal, the solution of the problem"of long-term weather forecasting.
