| Abstract: | The use of Yakeshi city 1961-2010 year annual average temperature,annual precipitation,wind,frost-free days of Yakeshi city in recent 50 years climate change and drought waterlogging occurrence characteristics.Analysis results show that:in the past 50 years,Yakeshi City,the annual average temperature is rising,the average increase of 0.32℃/10.The annual average temperature of wave crest and trough are clearly on the rise,which has 12-20 year cycle peaks,troughs have 10-16 year cycle;annual precipitation variation is not particularly evident;drought and flood occurrence probability of showing a tendency to increase;gale days showing a decreasing trend;frost-free period basically has no obvious change. |
