根据我站气象资料分析,77/78年冬期气候有如下几个特点:1,秋凉冬暖倒春寒.秋末天高云淡,气候凉爽.77年11月10日开始,日均温降到20.0℃以下,21日后降到15.0℃以下,中下旬的平均气温比历年平均值低1.2℃—2.0℃,胶树生长受到抑制.冬季(12月—2月)温度较高,12月气温有明显回升,旬平均温度升到15.0℃—18.0℃,与历年比较,月平均气温高1.8℃,月平均最低温度高1.9℃.1月和2月温度有所下降.最冷月(1月)平均气温为12.8℃,月平均最低气温为8.8℃,都比历年平均值高O.2℃;2月份平均气温和平均最低气温均比历年平均值高0.4℃.由于12月至2月气温连续偏高,春意盎然,多数冬眠作物陆续开始活动,胶树也提早萌芽.3月初开始,天气转为阴冷潮湿,中下旬的平均气温比历年平均值低1.2℃—1.6℃,胶树物候发育受到抑制.如表—1.
According to my station weather data analysis, 77/78 winter climate has the following characteristics: 1, autumn and winter and warm in the cold in late autumn sky clear, cool climate .In November 77, 77, the average daily temperature dropped to 20.0 ℃ The temperature dropped to below 15.0 ℃ after 21 days and the average temperature in the middle and late days was 1.2 ℃ -2.0 ℃ lower than the average value in the past years.The growth of Gum tree was inhibited.The temperatures in winter (December-February) , The average temperature of ten days rose to 15.0 ℃ -18.0 ℃, compared with the previous years, the average monthly temperature of 1.8 ℃, the monthly average minimum temperature of 1. 9 ℃ .In January and February the temperature decreased. The coldest month (January) the average temperature 12.8 ℃, the monthly average minimum temperature of 8.8 ℃, higher than the historical average O.2 ℃; February average temperature and the average minimum temperature 0.4 ℃ higher than the historical average. Since December to February the temperature continuously high In spring, the majority of hibernating crops started to move one after another, and the gum tree also germinated early .At the beginning of March, the weather turned cold and damp. The average temperature in the middle and late afternoon was 1.2 ℃ -1.6 ℃ lower than the historical average. Table-1.
