    Where don't you go to experience a continental climate?
    ::你到哪里去不经历大陆气候?

    There are no continental climates in the  Southern Hemisphere . Can you guess why? Continental climates are between 40° and 70°. The southern continents at this   are too narrow. All of their inland areas are close enough to a coast to be affected by the ocean!
    ::南半球没有大陆气候。 您能猜到原因吗? 大陆气候在40°到70°之间。 南部大陆范围太窄。 它们所有的内陆地区都离海岸很近, 足以受到海洋的影响 !

    Continental Climates
    ::大陆气候

    Continental climates are found in inland areas. They are too far from oceans to experience the effects of ocean  water . Continental climates are common between 40° and 70° north latitude.
    ::大陆气候存在于内陆地区,离海洋太远,无法经受海洋水的影响,大陆气候在北纬40度至70度之间很常见。

    Humid Continental Climate
    ::潮湿大陆气候

    Humid continental climates are found between 40° and 60° north latitude. The northeastern U.S. has this type of  climate . Summers are warm to hot, and winters are cold.   is moderate, and it falls  year  round.  Deciduous trees  grow in this climate ( Figure   ). They lose their leaves in the fall and grow new ones in the spring.
    ::湿度大陆气候在北纬40°至60°之间。美国东北部有这种气候。夏天热到热,冬天寒冷,温和,一年复一年。秋天树在这种气候中生长(图 ) 。 秋天树叶落空,春天长出新的树叶。

    Subarctic Climate
    ::地极气候

    Subarctic climates are found between 60° and 70° north latitude. Much of Canada and Alaska have this type of climate. Summers are cool and short. Winters are very cold and long. Little precipitation falls, and most of it falls during the summer. Conifer forests grow in this climate ( Figure   ).
    ::亚北极气候在北纬60度至70度之间。加拿大和阿拉斯加大部分地区都有这种气候。夏季寒冷短,冬季寒冷,冬季长,降水量很少,大部分降水量在夏季降水。在这一气候中,锥形森林生长(图 ) 。

    Summary
    ::摘要

    • Continental climates are far enough way from the ocean that there is no influence.
      ::大陆气候离海洋足够远,没有影响。
    • Deciduous trees are common in humid continental climates. Conifer forests grow in the subarctic.
      ::在潮湿的大陆气候中,贫瘠的树木很常见,在亚北极生长的松动林林。
    • Humid continental climates have warm winters and cold summers. Subarctic climates have cool short summers and very cold winters.
      ::湿润的大陆气候有温暖的冬季和寒冷的夏季,亚北极气候有寒冷的短夏和非常寒冷的冬季。
