This paper reviews the recent studies on the ionospheric weather and climate. As a national report prepared for COSPAR, the works concerned here are limited to those made by Chinese scientists during 2004-2006. The main contents include the sudden ionospheric disturbances, the ionospheric storms, the traveling ionospheric disturbances, ionospheric variability, the annual and semiannual ionospheric variations, the solar cycle ionospheric variations, and the long term ionospheric changes.
