Zy. Chen et My. Xia, PRIMARY VLF ELF CURRENTS PRODUCED BY HEATING THE LOWER IONOSPHERE IN PARTS OF CHINA, Electronics Letters, 30(23), 1994, pp. 1981-1982
A new iterative method is employed to calculate the primary ELF/VLF cu
rrents produced by heating the lower ionosphere with powerful modulate
d waves. The calculations are mainly for parts of China, as well as fo
r Tromso, Norway for comparison. The results indicate that, first, the
re are many similar characteristics for Beijing and Tromso, secondly,
the ELF/VLF currents in Haikou are much larger than those in Beijing a
nd Tromso if the natural electric fields are equal.
