| 摘 要： | 运用常规气象资料，对南宁市气温日较差的时空变化进行了分析，结果表明：南宁市气温日较差有逐年减小的趋势，夏秋季气温日较差大于冬春两季气温日较差，不同下垫面对气温日较差影响不同。对气温日较差较大的个例分析表明，引起气温日较差较大的主要天气系统为冷高压控制型、锋面影响型、暖低压影响型、副高影响型。

| Abstract: | The temporal and spatial variations of daily range of temperature were analyzed by using conventional data. The results show that there was a tendency of year-to-year decrease in daily range of temperature; daily ranges of temperature in summer and autumn were greater than those in winter and spring; the type of the underlying surface has great impact on daily range of temperature. Several case studies of obvious daily range of temperature were conducted, and the main influencing synoptic systems were the cold high, cold front, warm depress and subtropic high. |

| Keywords: | daily range of temperature synoptic system underlying surface |
