Abstract: Meteorological conditions are vital factors which cause various radio wave propagation effects such as refraction, attenuation, and trans-horizon propagation, etc. Radio meteorology is an interdisciplinary subject that studies the characteristics of the meteorological environment and mechanisms that affect radio propagation, and it is also an important research field of radio wave propagation. With the development of radio wave propagation, meteorology and related information science and technology, radio meteorology has continuously made new research progress which have provided more reliable data and mechanism support for the more reliable prediction of radio wave propagation and the application of radio systems. This paper comprehensively discusses the research progress in global digital mapping, radio parameter remote sensing and short-term forecasting, and gives a prospect for the development of the related directions in radio meteorology.
