Solar Microwave Quasi-periodic Pulsations with Multi-timescale and Fine Structures

Tan Baolin, bltan@nao.cas.cn, NAOC


Abstract
In most solar flares, the microwave quasi-periodic pulsations (QPP) are frequently observed at different frequencies. In this report, the author will introduce some recent observations of the microwave QPP with timescales from several decades of millisecond to several minutes. In particular, there are some fine spectral structures accompanying with the microwave QPP, such as millisecond spikes, zebra patterns, and fibers, etc. The author will also attempt to explain these complicated phenomena, and try to setup some links between these phenomena and the associated flaring processes.
