地理问题:都说低气压温度高,高气压温度低,但副极地低气压带和副热带高气压带哪个温度高啊!!到底是什么...
推荐回答(4个)
不是气压决定温度,低气压温度高,高气压温度低,这话说的应该不对
是温度决定气压,地球上各地的温度不同,主要的因素应该是太阳辐射的非绝热加热不同,而温度的不同进而导致了各地气压的不同,然而温度也不是决定某地气压的唯一因素,地形,天气系统等等都是可能因素
副极地低气压带和副热带高气压带,必然是副热带的温度比副极地的温度高
这两个气压带的形成主要是跟动力因素有关,也就是周围空气的运动强迫出来的,跟二者所处的温度关系不大
即:
副高的形成是由赤道低气压带上升的气流,由于气温随高度而降低,空气渐重,在距地面4-8公里处大量聚集,转向南北方向扩散运动,空气在向南北两极运动的水平过程中同时还受地转偏向力的影响,南半球向左偏,北半球向右偏,大约在南北纬30°附近逐渐偏转成西风(即环绕地球一圈向东吹),因此无法再向南北两极流,在南北纬30°附近的高空越集越多,最后被迫下沉,而在近地面形成副高.所以副高是由动力原因形成的.
当副热带高气压与极地高气圧的空气相遇时,暖而轻的气流爬升到冷而重的气流之上,于是又形成了一个上升气流,空气上升,空气就减少,气压自然降低。于是就形成了副极地低气压。
不能这样理解的
气压带的形成主要有两因素:
1、热力因素:赤道低气压带和极地高气压带——赤道附近地区是气温高,气流膨胀上升,近地面形成赤道低气压带;极地地区是气温低,气流收缩下沉,近地面形成极地高气压带。
2、动力因素:副热带高气压带和副极地低气压带——副热带地区是高空气流不断堆积导致气流下沉,形成副热带高气压带;副极地地区是来自极地高气压带的极地东风与来自副热带高气压带的西风在此相遇,来自副热带的暖气流被迫抬升形成副极地低气压带。
所以前者的形成是热力因素,后者的形成是动力因素,二者不能用气温高低比较气压高低,反之二者也不能根据气温高低比较气温高低。
当然是副热带高气压带温度高啦 一个靠近赤道 一个在极地附近查克可不是一点点呐。孩子 就你这问题来讲 不是什么决定温度高低 而是温度高低决定了气压(当然并不绝对 还有很多其它因素)而温度是由距太阳远近决定的呀!
懂了没???
