Show BETTER WEATHER FORECASTING Weather forecasting has been be placed on a n higher basis b by the discovery by Professor J 1 of ot the Geophysics institute of ot Ber gen Sen Norway that a n low pressure c area Is caused by two oppositely opposite directed air currents one ono hot bot and the tho other cold He explains Initially each current occupies about one half of the area covered by the depression The area of the cold air next nOt to the ground is at- at ata It om- om embraces a ways ays ays Increasing and finally braces the whole ol or the In the lower lavers layers The warm air r covers at the ground a correspond correspond- correspondIngly correspondIngly decreasing space As the tho do- do depression d develops ai ale air from the th warm warm sector all will escape upward and spread Into the higher layers The result Is a wind determined in direction and by th the temperatures and masses of ot the th moving air currents The motion slows s down as s soon coon as there Is only cold air supply available for forthe the tho ascending motion The tern tem temperature distribution In the do- do thus gives elves useful Indications Indica- Indica Indications ions concerning the expected tIe tIe- de The resulting air cur cur- currents currents rents when the opposing hot and an cold areas come into contact can cai be bo formulated mathematically as aa asan ai an equation giving the tho speed of ot the different masses of air relatively to toone toone t one another One may thus arrive at it a mathematical forecast pro pro- that sufficient data lata are on band hand A prediction made nade in this way from an ob erva Lion of or a in central Eu- Eu Europe Europe rope recently as was confirmed sub sub- subsequently sub Thus by a widespread gathering of o f data In this country covering air tir currents and temperatures the th weather forecast will m be greatly improved on |
