Show next two yeats years on sun will be cold colder ey scientist makes forecast of solar radiation washington its going to be colder on the sun for the next two years but who knows what will happen on the earth A long range forecast of solar radiation has just been made by dr charles G abbot secretary of the smithsonian institution find and published with the supporting data in an institution bulletin there is believed to be a very intimate relationship between the sun suns S wen weather ther and the earths weather but it its Is so extremely complex that as yet it Is not possible to make valid deduction from one to the other so abbot stresses the prediction has nothing to do with terrestrial temperatures for two years the average radiation of the great star into space from which the earth obtains the heat and light which make life possible still promises to be below normal it h has s been rather consistently higher than normal since 1030 1930 basis for prediction abbot bases his prediction on found by calculation in the solar constant ns trint the amount of radiation per square centimeter per second received at the outside limit of the earths atmosphere the normal value Is 1940 calories this varies with an extremely complex periodicity by observations and calculations extended ovelyea over years rs abbot has discovered the existence of seven such of 7 8 11 21 25 45 and 08 month periods which are intricately interwoven in making the two year prediction he combined the expected curves ot of ench each of these periods into one general curve two years ago lie ha made it similar prediction with less accurate data which in general has been fulfilled the sun as he predicted has given out considerably more heat than normal solar radiation important the fact that there will be a consistent although quite minute lowering of the amount of solar radIn radiation tion for two years hardly can help having nn an effect on temperatures on earth it does not necessarily mean however that there will be two cold years complex as 1 Is 1 solar so lar weather whether her on earth 1 Is vastly more intricate intorica t e it IL IP affected eted by mountains deserts vege vece tat oceans ocean e currents I 1 irrett snow c clouds I 1 buds humidity and winds which affect differently different localities nut but there Is little doubt that the varying influx of solar radiation Is one very important factor if it can be accurately predicted a very intricate problem will be greatly simplified ry by making these forecasts doctor abbot Is striving to solve this one aspect of 0 tile the problem then it mry may be possible to calculate one by one the effects of the numerous factors of terrestrial origin and find a method of predicting them in that flint event it would be possible to combine nil the predictions with the tested solar predictions and arrive at a valid valad long ions range weather forecast such ns as has been the brearn of meteorologists since the infancy of the science |
