文摘内容 Based on the radiosonde data observed at 14 stations in Southwest China from 1960 to 2010, as well as the corresponding surface air temperature, the long-term change of free-air 0 ℃isotherm height in Southwest China and the relationships between surface air temperature and 0 ℃isotherm height are discussed. The results indicated that the spatial distribution of 0 isotherm height is generally related with latitude, but the ℃ huge massif or plateau may complicate the latitude pattern. The two main regimes influencing the spatial patterns of 0 isotherm height℃ in Southwest China are latitude and huge massif. The annual 0 isotherm height has increased by 35 m per decade in the recent decades, which is st℃ atistically significant at the 0.001 level. Generally, the increasing trend can be examined for each seasonal series, especially in winter(53 m per decade). The diversity of trend magnitudes for annual and seasonal series can also be detected at a spatial view, but generally 0 ℃isotherm height correlated well with surface air temperature.
