These days, I found Shanghai’s Weather in early Oct is very like Sydney.
When I stepped out of the China Eastern Airlines flight MU562 from Sydney to Shanghai, I didn’t feel any difference in the temperature. I sweat a shirt in Sydney and in the noon time, a T-Shirt is OK. It is the same in Shanghai.
Later, I found out that it is exactly the date that Shanghai and Sydney are the same in weather.
The Two City Mirror Each Other Along the Equator
Shanghai is at 31°N 121°E;
Sydney is at 33°S 151°E.
On September 23, 2006, the Sun went directly onto the the Equator.
About 10 days after Sept 23, I guess the Sun moved to Sydney a little bit, so moved to exactly the middle of the two cities. Afterwards, Shanghai is going to autumn and winter, Sydney is going to spring and summer.
This time in Sydney, the biggest different in the South Semi-sphere for me is, the Sun shines on the north, instead of South in China.
