我站自记雨量计,3月份由保管室内拿出,作汛前试用检验,在试用的过程中,从自记纸上发现:20日8时至21日8时,全天晴天无雨,自记线自8时开始逐渐上升,17时后又逐渐下降,至凌晨2时停止,呈平直线维持到21日8时,又开始逐渐上升,且与前日自记线上升高度近似一致,17时后又逐渐下降,如此现象连续出现三天。晴天无雨雨量自记线为什么会较有规律的升、降呢?原因何在?经查阅“规范”及有关自记雨量计故障处理的书刊文件,对此现象均无记述。为了弄清原因守在仪器旁进行现场观察,证实这种现象不是由于人为的影响,只与日照温升有关。那么,温度又是怎样对它产生影响呢?
I stood to remember the rain gauge, taken out from the custody room in March for pre-flood trial test, in the trial process, from the self-record paper found: at 8:00 on the 20th to 8 at 8 o’clock on the 21st, no rain all day sunny, The self-recorded line began to rise gradually from 8 o’clock in the morning and gradually decreased after 17 o’clock until it stopped at 2 o’clock in the morning. It remained flat until 8 o’clock on the the 21st and began to rise gradually again. Then gradually decline, so there are three consecutive days. The reason why there is no regularity in the amount of rain without rainfall on sunny days? Why? After reviewing the “norms” and the documents concerning the troubleshooting of rain gauges, there is no description of this phenomenon. In order to find out the reasons for observing the scene by observing the equipment, confirmed that this phenomenon is not due to human influence, only with the rising temperature of the sun. So, how does the temperature affect it?
