I was born and raced in Seoul, Korea until I was 14. Our family moved to New Zealand and lived there since. Now I came to United States as an international student. I should say I've travelled quite a few countries. The contrast between winter and summer is striking.
Winter is bitterly cold and is influenced primarily by the Siberian air mass.
Summer is hot and humid due to the maritime pacific high. The transitional seasons, spring and autumn are sunny and generally dry. Temperatures of all seasons are somewhat lower than those at the corresponding latitudes in other continents, such as North America or Western Europe. The variation of annual mean temperature ranges from 10oC to 16oC except for the mountainous areas. As New Zealand in an island nation set in the Southern Oceans, the weather can be very unpredictable.
