我是山西人，我家乡的气候真的是可以用“变化莫测”来形容的，当然这个和山西省的地形有关系。 首先说一下春季，我们那里春季升温很快，往往在2月或3月就会进入暖季，但是温差很大，常常是白天艳阳高照，晚上狂风大作，温度骤降到0度以下。这个时候往往会有大风雪天气，有时候甚至半夜睡醒一开门发现整个天地白茫茫一片。不过这种天气不会持续很久，大概就一个星期左右时间。
其次是夏季，我们的夏天可以说是很完美的，气温高而且阳光充足（虽然有的时候会下雨），非常有利于各种农作物生长。但是夏天的天气变化也很大，说晴转阴晴转雨都是常事，有时候前一天还烈日当空，第二天就可能暴雨如注。
到了秋季，我们那里的气候开始变得稳定，昼夜温差比较大，白天热，晚上凉。秋雨也是多而频繁，往往是早晨起来天晴朗，中午吃完饭天空就开始变暗，下起蒙蒙细雨，一直到傍晚都不会停，让人防不胜防。
冬季的到来总是伴随着大雪，每年都会下几次暴雪，路面都是白雪皑皑，车辆都行驶缓慢，不过这样的天气对我们来说已经很稀罕了，毕竟现在冬季空气已经明显变暖。
洪玄忻优质答主As far as I know， my hometown is in the southern China， which lies along the river basin. There are four distinct seasons in this area: hot summer， cold winter， rainy spring and windy autumn. Nowadays， the climate in my hometown is changing dramatically with the development of human beings.
I can still remember that when I was studying in the primary school the summer used to be quite hot but cool after 6 pm. And the spring is usually accompanied by light rain， but now it is getting harder and harder to have a beautiful light rain in my hometown during the spring. In recent years， many natural disasters happened in the south of China， such as drought， hail， flood and landslide， and they occur much more frequently than before. All of these changes are due to the greenhouse effect.
Therefore， there are more and more campaigns organized to call on people to care about our environment and protect climate. I think that the best way to prevent the global warming from being more serious is to take everything from our daily life. For example， we can take the bus or subway instead of taking the taxi. We can use the cloth bags instead of plastic bags when shopping.
As one of the fast growing countries， China is playing a vital role in environmental protection. I believe that the global effort can make the earth better and better.
