Why is the recent weather forecast often inaccurate? The predicted temperature is much worse than the actual temperature, and sometimes rain is reported as dust?

If a rainy day turns into a sandstorm, it is really a matter of weather forecast, but you should pay attention. Is it a forecast after all? Prediction means that this is a probability, which means that there will be errors. In addition, as upstairs said, under the background of global warming, the weather changes will become more and more complicated, and it may be necessary to establish a new mathematical model to predict the weather more accurately.

If the predicted temperature is much worse than the actual temperature, it is not necessarily that the weather forecast is inaccurate, because the temperature measurement is not just to put the thermometer in the open air as you think. This is an industry norm. In general, thermometers are placed in ventilated shutters that are not directly exposed to sunlight for temperature measurement. Of course, you will feel that the temperature predicted by the TV station is different from what you feel. This phenomenon will be more obvious if you live in an urban area, because cities can be formed.
