Abstract:

In order to refine and fully verify the accuracy and applicability of the high frequency prediction method, a refined method which is more suitable for China and surrounding areas is discussed, which is even extensive by used in the Asia area. The MUF and OWF of two circuits are calculated by using the China refined HF frequency prediction method, and are compared with observations. The result show that (a) the predictions are in great agreement with the monthly median statistical characteristics of observation data, and (b) the accuracy is analogous to that in the China region.

Key words: HF communication, frequency prediction, refined method, except in China domain, long distance
