JOVIAN S-BURSTS - A DISCUSSION ON THE S-BURST DRIFT MODEL

Refering to Riihimaa's classification of Jovian S-bursts, type f displ ays both positive and negative drift rates. By simulating the structur e of a typical type f burst, we discuss the fitting of the instantaneo us drift rate of a given S-burst as a function of the frequency in the frame of trapped electrons hypothesis. We show that it is not possibl e to fit this drift rate for fixed values of the pitch angle and the e nergy of the electrons generating the burst.
