Sir, please check my expression for this picture.
These charts show the differences of annual temperature and rainfall of two cities: Sao Paulo in Brazil and Lagos in Nigeria.
Between these two cities through a whole year, there are little differences in the change of temperature. Both of them see a gradual decrease from around 35c between February and March to the lowest point during June to July. But the temperature in Sao Paulo is only 20c in July, lower than 30c in Lagos. Since August, their temperature rates have begun to rise until spring of the next year.
However, there is a huge difference in their rainfalls. In Sao Paulo, while March sees a rise, rainfall in the first half of the year has been on a decrease, reaching a mere 50mm in June. From then on, the figure keeps an upward trend until December. In contrast, Lagos sees an opposite trend: the lowest 50mm rainfall in January but the higher 340mm in June.
To sum up, while Sao Paulo has similar pattern in temperature as Lagos, their rainfalls through a year are very different.
