摘要
Global climate change has a wide range ofimpacts,and this paper presents an investigation onhow global warming has changed the relationshipbetween air temperature and latitude & altitude usingthe meteorological data obtained from 160 stations inChina. The investigation indicates that there are verydistinct seasonal differences in patterns of tempera-ture variation as a function of latitude and altitude:avery significant latitude effect in winter and a verysignificant altitude effect in summer. However,withglobal warming,the latitude effect in winter isweakening and the altitude effect in summer isstrengthening. This pattern of change in therelationship between temperature and latitude &altitude is helpful in efforts to reconstruct and explainthe past temperature patterns and variations.
