China’s extreme size means it has a great diversity of climates, but being located entirely in the northern hemisphere means its seasonal timings are broadly comparable to those in Europe and the US. The northeast experiences hot and dry summers and bitterly cold winters. The north and central region has almost continual rainfall, hot summers and cold winters. The southeast region has substantial rainfall, with semi-tropical summers and cool winters. Central, southern and western China are also susceptible to flooding, and the country is also periodically subject to seismic activity.
