TREND ANALYSIS GROUPING OF STATIONS BY AVG TEMP CHANGE AND LATITUDE DURING THE LAST 50 YEARS The 10 temperature groups are (°C) : -> -1.0, -1.0 -> -0.5, -0.5 ->0.0, .....+2.5 -> +3.0, +3.0 -> The 6 latitude groups are : 0->30S, 30->60S, 60->90S, 0->30N, 30->60N, 60->90N Selection : all stations Comp. procedure :Linear regression TEMP.INTERVAL NO OF LATITUDE DISTRIB.
