Abstract To solve the problem of too much time spending on calculating the distribution of radar detection range over sea, firstly ,the method characteristic of calculating radar detection range in condition of evaporation duct is described, the influence of evaporation duct height, the bulk Richardson number and wind speed on radar detection range is presented, then consulting table method based on this influence is advised to use for calculating radar detection range of each weather record over sea and the principle of constructing standard radar detection range table is outlined. The calculating time is greatly shorten by means of consulting table method, the result difference between consulting table method and that of direct calculation is small, so this method can meet the requirement of summarizing the distribution of radar detection range over sea quickly.
