Weather differences

I will compare the weather in Adelaide with Seoul's weather.
Firstly, Korea has four seasons per year. Each season is composed of 3 months and, currently, the Korean season is summer. It's very hot and humid in summer. It also rains for a long time. Thus, this excessive rainfall causes floods every year. It is one of the biggest problems in Korea.
However, Adelaide has three seasons which are summer,fall and winter. Australia is in the southern hemi-sphere, so all seasons are different from Korea during the same period. For example, in June in Korea it is now summer. However, in Australia, it is now winter. Usually, in
Australia, the amount of rain in winter is much more than in summer. So, nowadays, the weather is windy and rainy. But without this winther period, the atmosphere would be really dry and this would affect the population's life style. So, a huge part of this continent is desert.
Secondly, snow is a huge difference between these cities. We don't see snow in Adelaide, because it isn't cold enough to be freezing here. But in Korea, during the midterm of wnter, there is a lot of snow. the average temperature is below freezing point at that time.
I think these things are major differences between Korea and Australia, but I have yet to prove them to mself by living here for an extended period of time.
