地球上有位置只有一个季节?

我在寻找地点/地方/国家只有一个赛季。

不同的季节,我的意思是一个大的变化引起的温度和降水气候地区。我不是寻找异常天气。

回答

该地区显示地球上最小的对比季节是在赤道附近,因为较小的太阳辐射的变化。因此,赤道地区不经历寒冷和温暖的季节。相反,大多数赤道地区通常有湿和干燥的季节转变的[热带辐合带(ITCZ)][1],这是一个乐队的云层和大雨,环绕地球。考虑到这一点,一个好的起点至少发现地区季节性对比(即一个赛季)是赤道附近找地方ITCZ少变化。下面是图显示的最大向北和向南位置ITCZ年内(从[这][2]但我添加了赤道线红色)。[![在这里输入图像描述][3]][3]通过观察ITCZ如何变化,看起来你是寻求在巴西北部的地方。不过这只是粗略thoerization。我们可以进一步通过观察实际数据。因为没有一个气象站在地球上每一个位置,我们最大的希望是使用再分析数据。 This is basically data computed using all available weather station data to figure out atmospheric variables all around the world. One of the most reliable reanalyses is ERA-interim covering the period 1979-2018. This data can be accessed and queried at [KNMI Climate Explorer][4]. Using the analysis tools there, I've computed standard deviation of the monthly precipitation over the whole Earth for each of the 40 years cover by the dataset. Then, I've averaged those 40 years to see where the precipitation has the least variation through the year (within that 1979-2018 period). I downloaded the data to better visualize and analyze it and it looks like this: [![enter image description here][5]][5] As was to be expected, the smaller variation happens in the drier places. This is because the total precipitation is small and thus the standard deviation will be small as well. For example, if in a dessert it rains only 10 mm in any month, the maximum possible precipitation variation will be 10 mm, despite still being a big contrast between seasons. But in a tropical forest it might rain 400 mm in the driest month and 420 mm in the wettest, a difference of 20 mm, yet still have a negligible seasonal contrast. All that is to say that if we care about seasonal variability, it makes more sense if we show the standard deviation above then normalized by the total precipitation, which looks like this: [![enter image description here][6]][6] As we anticipated looking at the changes in the ITCZ, the most apparent equatorial area with minimal contrast between wet and rainy seasons is in northern Brazil/southern Colombia/northeastern Peru. But there are also some lesser areas in northern Congo in Africa and Indonesia in Asia. [climatemps.com][7] have a nice map where you can click stations around the world and see climate stats. If you click stations there that are in the area encircled by the blue blob near northern Brazil in the above figure, you will indeed see several pretty flat temperature and precipitation curves. For instance for Iquitos, Peru: [![enter image description here][8]][8] To better compare with the example of Andagoya, Colombia provided in other answers, here is the same data but with the axis scaled to match the Andagoya figure: [![enter image description here][9]][9] So those areas of equatorial South America and Africa appear to indeed be some of the least varying places through the year on Earth.
