据报道，孟加拉国饱受气候变化之苦，当地民众开始怀疑孟加拉国年历中的六季会过渡到四季。我们从达卡气象站收集了关键气候变量的观测数据，并对1,011名受访者和7名专家进行了调查，以确定六季是否正在变成四季。为了科学地识别这一点，我们将非参数统计方法应用于气候变量，并测试是否有任何一对相邻的两个季节收敛为一个。统计分析显示，特定的两对两个相邻季节的“收敛”，这意味着每年的日历现在由四个季节组成，而不是六个季节。65%的受访者认为，每年的日历过渡到四季。结果表明，气候变化的影响变得明显的程度，人们正确地感知到一些基本的季节变化。
Bangladesh is reported to suffer from climatic changes, and local people begin to wonder that six seasons in Bangladeshi annual calendar transition to four seasons. We collected observations of key climate variables from the weather station in Dhaka, and conducted surveys with 1,011 respondents and seven experts to address whether six seasons are becoming four seasons. To scientifically identify this, we apply nonparametric statistical methods to the climate variables and test whether any pair of two neighboring seasons is converging into one. The statistical analysis shows “convergence” for specific two pairs of two neighboring seasons, meaning that the annual calendar now consists of four seasons, not six. The 65 % of respondents believe that the annual calendar transitions to four seasons. The results imply that the effect of climatic changes becomes evident to the extent that people correctly perceive some fundamental seasonal changes.
