Observations have shown that the debris dis- persed rapidly throughout the tropics with incursions into the temperate latitudes of both hemispheres. Only relatively light concentrations of debris occurred away from the immediate vicinity of the explosions. Foreign countries have also had their weather anomalios: Below normal rainfali in Germany and northern Europe, floods in the Danube basin, unusually rainy weather in Japan, and so forth. eeoeweecneeean ee ee ee ee ee @eneerenvcer es toe ee ee ee eee ree et eeeres Oe soe eevee ew een e ss esa ees eee ew we ee see ewe aer eee er eee soe # ee wee wmee nm awe ewes @eegaeetes epeweseaeeneenpvbeneseeerteensvpe eeeseaene Peeoeeeeeweeeseeeeteeewne seve eevpvreeeseeeseseetceaeesteseesteseeeepeewtesase tees ereteaetereevrt See soe rp Oe e eG BS eS eee ee we ee eee eee esewmeeeetesuseneeeereert wee se Sea sese ae e ee ere ec Steere see eee ree tee ea eee eee anee te eee ee ea ene . eseeeseeseeoeane & Be Puede eweeneeseeeaerteeenrtreea: eoeetaqaeeeaespetarvrasea oe ses@ te ee eeeerPtss etree **+ eaeseeaensteere#ktertr eesseoewaeeeerevr tee ce we eeseepeneeeseeeaeer *@ + se Ce ese ween ease en we eee eoeose epeseeeteeeeveeeneereaeee @Peseveseneeveaeereeertetee tt BP @w@ernrtetere ew Bee & #8 8 GS He te ee em re tee ore wee eee seeoe eme ew eweownweewnesaVW9wner tee . esee esa e+ ewe es ee empenereeete e He Be > Yet He ee | eee eo emai eeeesevre ee ee ee ee ed eee wees * © *#eeseo@eeuseenerPteteasevenwr *@eenpneeeee@eeeeepesepeseeoeesetie ew eve eee aaa Be many of these e stations in the United States axperienced approximately normal rain- fall. cz If bomb debris affected the weather and if the debris had played @ meesurable role in the precipitation process ag ig claimed by some, one might expect that weather forecasters who were not avara of the Pacific tests when their predictions were made would have produced poorer forecasts. 2 «et m 7 | Om the contrary, however, there has been no departure during the Spring of 1954 from the normal expectations of accuracy in weather prediction which has been established in previous mM ; L " fel = 9 Zz fa uM ei REPRODUCED AT THE DWIGHT D. pee f:3 ne os 7 “1 . ‘ “oF 7 2
