Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed by China Meteorological Administration. This standard by the National Artificial Weather Standardization Technical Committee (SAC/TC538) centralized. This standard was drafted unit. Wuhan regional climate center, artificial weather in Hubei Office. The main drafters of this standard. Zhou Yuehua, Guo Guangfen, to Yuchun, to China. Air water vapor resource calculation method

1 Scope

This standard specifies the calculation method of single station and regional airborne water vapor resources. This standard applies to water vapor monitoring, evaluation.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Atmospheric precipitable water Total water vapor per unit area of the bottom column is converted to the height of the equivalent liquid column. 2.2 Air water vapor resources atmosphericwatervaporresource A certain area of the whole layer of precipitation can be atmospheric. 2.3 Water vapor - precipitation conversion rate watervapor-precipitateconversionratio Precipitation over a period of time and the ratio of atmospheric precipitable water.

3 calculation method

3.1 atmospheric precipitable water calculation method 3.1.1 Calculation method based on sounding meteorological data [see formula (1)] PW = - 10ρg∫ pz p0 q (p) dp (1) In the formula. PW --- whole layer of atmospheric precipitation, in millimeters (mm); ρ --- density of liquid water, in grams per cubic centimeter (g · cm-3); g --- Gravitational acceleration, in meters square second (m · s-2); p --- calculation layer pressure, in units of hectopascals (hPa); p0 --- ground pressure, in units of hectopascals (hPa); pz --- z altitude pressure, in hPa; q (p) --- Calculate the layer specific humidity, in grams per kilogram (g · kg-1), calculated as. q (p) = 622e/p In the formula. e --- vapor pressure, in units of hectopascals (hPa), the formula is. e = 6.11 × 10 [7.45td/(245 td)] td --- calculation layer dew point temperature in degrees Celsius (℃). ......
