  • 热带湿润气候

    What kind of climate is this?
    ::这是什么气候?

    Whether a place is wet all  year  round or dry for some time really affects what can grow there. In the tropics, places that are wet year round have lush vegetation. Places that are dry some of the time are much less lush.
    ::某个地方是全年湿润还是干燥, 一定时间都会影响那里的生长。 在热带地区, 潮湿的一年有茂密的植被。 部分时间干燥的地方的干燥程度要低得多。

    Tropical Climates
    ::热带热带气候

    Tropical climates are found around the  equator . As you'd expect, these climates have warm temperatures year round. The warm air rises at the equator. As it rises, it cools, causing it to  rain . Tropical climates may be very wet, or wet and dry.
    ::热带气候存在于赤道周围。 正如你所预期的, 这些气候是全年的温度。 赤道的温暖空气会上升。 随着赤道的上升, 它会冷却, 导致降雨。 热带气候可能非常湿润, 或者湿润和干燥。

    Tropical Wet Climate
    ::热带湿湿气候

    Tropical wet climates occur at or very near the equator. They have high rainfall year round.  Tropical rainforests  ( FIgure   ) grow in this type of  climate .
    ::热带雨林(Figure)在这种气候中生长。

    Tropical Wet and Dry Climate
    ::热带湿湿和干旱气候

    Tropical wet and   occur between 5° and 20°   and receive less rainfall. Most of the rain falls in a single season. The rest of the year is dry. Few trees can withstand the long dry season, so the main plants are grasses ( Figure   ). Wildlife thrive on these grasslands.
    ::热带雨量在5摄氏度至20摄氏度之间,降雨量较少,大部分雨量在一季降下,其余时间是干燥的,很少有树木能够承受漫长的旱季,因此主要植物是草(图 ) 。野生动物在这些草原上生长。

    Summary
    ::摘要

    • Tropical climates are found at or near the equator. Because warm air rises at the equator, there is a lot of rain.
      ::赤道附近或赤道附近都有热带气候,因为赤道有温暖的空气,因此降雨量很大。
    • Tropical wet climates get rain year-round. Tropical rainforests grow in this climate zone.
      ::热带热带湿气候全年降雨,热带雨林在这一气候区生长。
    • Tropical wet and dry climates have a rainy season and a dry season. The vegetation is largely grass.
      ::热带潮湿和干旱气候有一个雨季和一个旱季,植被主要是草。
