The influence of weather on business.

Bad weather will lead to a decline in business performance. For example, extremely hot or cold weather will affect people's travel and psychology, which will lead to a decline in performance. Of course, different weather has different effects on different commodity industries. Rainy days can increase the output and sales of umbrellas. Of course, the sales of shops and grocery stores will be less than when the weather is good. Different industries have different reactions to weather changes, less to necessities and more to unnecessary ones.
