Zusammenfassung |
The characteristics of VHF radiowave
scintillations at 244 MHz (FLEETSAT) during a complete solar cycle (1983–93) at
a low-latitude station, Waltair (17.7°N, 83.3°E), are presented. The
occurrence of night-time scintillations shows equinoctial maxima and summer
minima in all the epochs of solar activity, and follows the solar activity. The
daytime scintillation occurrence is negatively correlated with the solar
activity and shows maximum occurrence during the summer months in a period of
low solar activity. The occurrence of night-time scintillations is inhibited
during disturbed days of high solar activity and enhanced during low solar
activity. |
