troposphere
意味: The lowest layer of the Earth's atmosphere, extending from the surface to roughly 8-15 kilometres altitude, where almost all weather occurs and where temperature generally decreases with height.
The troposphere contains approximately 75 per cent of the atmosphere's mass and virtually all its water vapour, making it the domain of clouds, rain, storms, and all familiar weather phenomena. Its upper boundary, the tropopause, marks the transition to the stratosphere. The thickness of the troposphere varies: it is deeper at the equator and shallower at the poles. Rising greenhouse gas concentrations in the troposphere are the primary driver of global warming. It collocates with 'weather,' 'temperature,' 'greenhouse gases,' 'ozone,' and 'altitude.'
例文
- All commercial aircraft cruise near the top of the troposphere, where the air is thin enough to reduce drag but dense enough to provide lift. 所有商用飞机在对流层顶部附近巡航,那里的空气稀薄到足以减少阻力,但密度足以提供升力。Todos los aviones comerciales vuelan cerca de la parte superior de la troposfera, donde el aire es lo bastante tenue para reducir la resistencia aerodinámica pero lo suficientemente denso para proporcionar sustentación.すべての民間航空機は対流圏の上部付近を巡航しており、そこでは空気が十分に薄いため抵抗が小さく、かつ揚力を得るのに十分な密度があります。모든 민간 항공기는 대류권 상부 부근을 순항하는데, 그곳은 항력을 줄일 만큼 공기가 충분히 희박하면서도 양력을 발생시킬 만큼 충분한 밀도가 있습니다.
- The Met Office uses weather balloons to measure temperature and humidity throughout the troposphere twice daily. 英国气象局每天两次使用气象气球测量整个对流层的温度和湿度。La Met Office utiliza globos meteorológicos para medir la temperatura y la humedad en toda la troposfera dos veces al día.英国気象庁は1日2回、気象バルーンを使って対流圏全体の気温と湿度を測定しています。영국 기상청은 매일 두 차례 기상 풍선을 사용하여 대류권 전체의 기온과 습도를 측정합니다.
- Greenhouse gases trapped in the troposphere absorb outgoing infrared radiation, warming the planet's surface. 对流层中截留的温室气体吸收向外辐射的红外线,使地球表面升温。Los gases de efecto invernadero atrapados en la troposfera absorben la radiación infrarroja saliente, calentando la superficie del planeta.対流圏に閉じ込められた温室効果ガスは外向きの赤外線放射を吸収し、地球の表面を温めています。대류권에 갇힌 온실가스는 외향 적외선 복사를 흡수하여 지구 표면을 따뜻하게 합니다.
