| 低海拔地区冬季由于凝冻常常会使风向风速传感器冻结，造成风要素资料失真或监测数据缺测，影响数据可用性，造成气象数据历史延续空白，导致无法弥补的历史数据损失。该文利用三穗县国家基准气候站2008—2020年冬季逐日、逐时、逐分钟风向风速、气温、相对湿度以及降水等地面气象监测资料，详细分析冬季冰冻期间风向风速缺测时段的气温、相对湿度、降水等相关信息，找出风向风速冻结与气温、相对湿度、风速大小的对应关系，从而判定风向、风速易冻结的气象要素阈值，采用USB碳纤维发热片，科学搭建低压加热方式，确保风向、风速传感器设备加热时不被灼伤受损，ZQZ-TF风向、风速监测资料连续可靠。 |

| Abstract: |
| In winter at low altitude, due to freezing, wind direction and speed sensors are often frozen, resulting in distortion of wind element data or lack of monitoring data, affecting data availability, resulting in continuous blank of meteorological data and irreparable loss of historical data. In this paper, based on the daily, hourly and minuter-by-minute surface meteorological monitoring data of wind direction and speed, temperature, relative humidity and precipitation from The National Reference Climate Station in Sansui County from 2008 to 2020, the temperature, relative humidity and precipitation during the unmeasured period of wind direction and speed in winter were analyzed in detail. The corresponding relationship between wind direction and wind speed freezing and air temperature, relative humidity and wind speed is found out, so as to determine the threshold of meteorological elements that wind direction and wind speed are easy to freeze. USB carbon fiber heating sheet is adopted to scientifically build low-pressure heating mode to ensure that wind direction and wind speed sensor equipment will not be burned and damaged during heating and ZQZ-TF wind direction and wind speed monitoring data will be continuous and reliable. |
