The operational system software currently used in radiosonde stations has the function of automatic correcting, i.e., to modify the temperature pressure moisture curve automatically. But in practical applications, if only relying on the automatic correction to process the abnormal data, it maybe cause the distortion or inaccuracy of measurements. In order to avoid the shortcomings of the software and ensure the accuracy and comprehensiveness of the first hand sounding data, it is necessary to carry out human intervention in abnormal data processing. Some examples from Dongyuan Station are used to illustrate the necessity of human intervention， and the methods of human intervention and the issues that need attention in human intervention are discussed.
