Abstract

NE China is at the Northern Hemisphere (NH) extratropical latitudes, whose climate shares many features with the climate at these latitudes. The study shows that since the 1880s the temperature of NE China has been rising in a fluctuating manner, with one peak in the 1940s and since the 1980s to the present the temperature has broken the record of the past 100 years, arriving at a new level. Statistical evidence indicates that since the 1880s NE China has experienced the temperature rise of 0.6~1.1⁰C, a trend in agreement with that of the NH change. On the other hand, the precipitation has not shown pronounced variation in this period but exhibited dry and wet stages, with the dominant periods spanning ~11 and ~22 years. In the past 30 years the heat condition in this region has been improved greatly, where ≥10.0⁰C cumulative temperature values have been increased remarkably. Following research results available it is inferred that the factors affecting the climate change in this region probably include CO₂, circulation, sea surface temperature, anthropogenic activities etc. Climate change will impact inevitably on agriculture and ecology, and initial assessment is made of the climate impact, together with countermeasures and suggestions presented.
