\n\n（2）降水量一般采用2段制进行观测，即每日8时及20时各观测一次，雨季增加观测段次，雨量大时还需加测。日雨量是以每天上午8时作为分界，将本日8时至次日8时的降水量作为本日的降水量。若为降雨，用20专用量杯量测，当降雪时，仅用外筒作为承雪器具，然后用电子天平（沈阳龙腾ES30K-12型号电子天平，最小感量为0.2g）称重测量。

If there is precipitation between 20:00 of the previous day and 20:00 of the current day, the calculation formula is: evaporation = original amount + precipitation - allowance.
\n(2) The precipitation is generally observed in two-stage system, i.e. once at 8:00 and once at 20:00 every day. In rainy season, the number of observation sections is increased, and when the rainfall is large, additional measurement is required. The daily rainfall is defined by 8:00 a.m. of each day, and the precipitation from 8:00 a.m. to 8:00 a.m. of the next day is regarded as the precipitation of the day. In case of rainfall, use 20 special measuring cup to measure.
