摘  要：
以潮州50年的气象资料为基础,分析了农业气候变化的特征和规律。结果表明,近20年潮州的年平均气温呈明显的上升趋势;各季的升温幅度不同;近20年夏季高温天气明显增加,低温霜冻、低温阴雨、寒露风天气减少,特别是近10年来更加明显;降水季节性变化明显,降水偏多的年份、季节往往气温较低;20世纪90年代中期开始气温和降水都呈上升趋势,但气温上升的幅度比降水明显偏大,另外,降水偏多的时段主要出现在夏季、秋季和冬季,即夏季高温多雨,秋、冬季暖湿;降水偏少的春季气温明显偏高;虽然近年来气温呈明显上升趋势,高温、暖冬经常出现,但是强度较强的低温霜冻、低温阴雨、寒露风天气仍会出现,极端强降水天气也时有发生。
