weather of Melbourne

i do not like the weather of Melbourne, it changes randomly, sometimes you go out, and the sky is blue without cloud and wind. but maybe 10 or 20 minutes laters, it changes. cloud full of the sky, the sky turns dark, and start rain. and the difference in temperature is huge. sometimes, the highest temperature is 35℃, but the lowest one maybe 20 or even lower. in the situation, people are easy to get sick such as cold or fever. but maybe the Aussie strong enough or already are used to the weather, i do not hear Aussie complaint about the weather. in constrast, some students like me, you know international students, are often complaint about the weather. especially me.
before i went to Liaoning Uni, i lived in a small city called Dandong in the northeast of China, and east of Liaoning Province. it is a small city without so many crowd, and not developed, but still developing. not busting like other big city such as Beijing or Shanghai. but i think the weather of Dandong is perfect, not too hot in summer, and not cold in winter. and because of the location of the city, the air there is not too dry. every stuff about weather in Dandong is very good. i really mean that. i travelled a lot, and have been some cities, but none of this city can compared with Dandong in weather perspective. some cities are too hot in summer such as Sanya and Hong Kong. and some cities are too cold in winter such as Harbing. some cities do not have clean air such as Fushun. after graudated from high school, i entered Liaoning Uni, in Shenyang ,the capital city of Liaoning Province. because my grandma lived in Fushun, i go to Funshun every year, Fushun is very close to Shenyang, so sometimes i went to Shenyang for shopping when i was young. in my memory, the air of Shenyang was not so clean due to some heavy industry. but when i went to Shenyang for studying, i noticed that Shenyang has Changed a lot, the air gets clean. very good. but in spring, the wind is so so big. when there winds, the air is no more clean, full of sand. what a pity. after two years study in Liaonning, i went abroad, LOL. come to Melbourne. at first i thought the weather here was good, because the sky is so clean, and the air is clean too. but when i live here for a while, i noticed that, i could not stand the temperature, it changed so quick. Melbourne is good, but its weather is not good as the city. and i believe that the people work in the Melboure Weather Bureau is not easy, esspecially weather expert, because the weather here changes so quick and random, it is not easy to forecast the weather. but i also noticed that most of the weather forecasting is correct, very good job.
