What is an unusually bad climate?

In fact, people often say that the climate is abnormal. Generally, the climate is not bad, and the weather is bad, such as bad weather.

So, what is climate anomaly? The climate value of a meteorological element is the result of many years' average, usually 30 years' average. If a year (or a quarter or a month's value) is significantly different from the average climate, it is called climate anomaly. For example, the average temperature in a certain place is 30 degrees in summer and 40 degrees this summer, which is called climate anomaly.
