The month average and the year average water vapor press in chongqing both show that : the water vapor press decreases with the increasing of sea level elevation ; the water vapor press values in north - west and middle hill areas are middle and high ; the water vapor press values in north - east and south - east mountain areas are relatively low. the sea level elevation in north - east and south - east mountain areas of chongqing is higher, especially the north - east mountains are more rugged than the north - west mountains, and the decreasing of water vapor press with the increasing of sea level elevation is more distinct, so the lowest value often appears in the north - east mountains not in the north - west mountains. the seasonal change of water vapor press in chongqing is also distinct : the values of water vapor press are low mostly in winter, and the high values are relatively less ; the values of water vapor press are middle and high mostly in summer, and the low values are relatively less, the values in spring and autumn are between them
重慶市全年各月月平均和年平均水汽壓都表現出：隨著海拔高度的增加，水汽壓逐漸減小；西北部和中部的丘陵低山地區一般為水汽壓的中高值區；東北部與東南部的山地地區的水汽壓則相對較小重慶市東北東南山地地區海拔高度較高，尤其是東北山區的山地較東南山區的起伏更大，水汽壓隨海拔高度的減小更加明顯，因此各月的最小值往往出現在東北山區而非東南山區重慶市水汽壓的季節變化也很明顯：冬季水汽壓多為小值，大值較少；而夏季多為中、大值，小值較少；春秋季則介於兩者之間。
