Ponchow is warmer than Tokyo and Lanchow in, winter and hotter. than they in summer*. It is because they are Located at different Latitudes. Foochow, being located at las lover Intitude than the other two cities,

is beater more intensively by the sun in both seasons. The sun's rays, which foll on Foochov at a larger angle, bring more heat since they have traveiled through: shorter distance ru Lie atmosphere and spread over a smaller
