| |
| Abstract: | The paper aims to provide meteorological service for preventing and reducing disasters. The authors studied the drought variation characteristics during 1961-2015 by means of mathematical statistics,Z index and Mann-Kendall test based on the monthly precipitation data during 1961-2015. The results indicated that: the climate of annual precipitation in Chuzhou had a wetting trend, spring and autumn showed a drought trend, and spring drought trend was obvious; while the climate of summer and winter had a trend of wetting, however, it was noticeable that drought was the main trend of winter climate during 2006-2015. Drought of year and drought of spring which were above great drought occurred once every 5-6 years; continuous drought of season by season occurred twice every 5 years; the frequency of drought which was above great drought occurred twice every 7 years in winter, once every 6 years in summer and once every 8 years in autumn. |
