Based on data from Russian and Chinese ionospheric stations and GPS network data
ionospheric disturbances were investigated in the Eastern Siberia and the Far East during the
second half of September 2005. Under quite magnetic conditions a growth of critical frequency
and minimum height F-layer variation intensities were recorded. These changes had periods about
1.5-6 h. As a rule the growth of intensity was attended with the detectable deviations of F2-layer
parameters from their medians. At the same time the magnified intensity of disturbances in total
electron density was registered with specific temporal scale about 60-90 minutes. The quite
geomagnetic conditions suggest that these disturbances probably can be associated with intensive
tropic cyclones DAMREY, SAOLA, LONGWANG.
Keywords: ionospheric disturbances, tropical cyclones
