本文选取1961—2013年宁波鄞州气象站地面观测数据，运用趋势分析、突变分析、相关性分析等方法，开展宁波地区高温期水热变化研究.得出以下结论：1)自1961年以来，宁波地区高温期温度和降水呈缓慢上升的趋势，相对湿度出现明显下降，其中温度上升是导致该地区相对湿度下降的主要因素；2)相对湿度变化在20世纪末、21世纪初出现突变，突变后相对湿度下降更加明显，有明显向“暖干”气候转变的趋势；3)2000—2013年，高温天气下的温度与相对湿度呈现明显的负相关，温度与相对湿度的相关系数达到了历史最高值0.633.高温天气成为近10年来相对湿度明显下降的决定性因素.

Ground observation data at Yinzhou weather station in Ningbo were used to study changes in precipitation and temperature during high-temperature periods.Trend analysis, mutagenesis analysis and correlation analysis were done.It was found that from 1 961,temperature and precipitation in Ningbo showed a constant increase trend,while relative humidity decreased progressively.The rise in temperature was a key factor for decrease in relative humidity.Relative humidity changed abruptly in the early part of this century. Relative humidity decreased more obviously from then on. The climate had become warmer and drier. Temperature and relative humidity showed a significant negative correlation in high-temperature periods from 2000 to 2013.The correlation coefficient between temperature and relative humidity was the highest value of 0.633.High temperature weather is a crucial factor in the obvious decrease in relative humidity in these years.
