Is the weather forecast 14 accurate?

Recently, the sky is too abnormal, and many situations are beyond the range that people can predict, so it is difficult to predict. However, because the low altitude is affected by very complicated factors near the ground, the current forecast is mainly made by forecasters on the basis of statistical forecast and using comprehensive judgment method. In Nanjing and other places, it often rains on cows' backs these days. It rains heavily in some places, but it doesn't rain in the street next door, and even there is a situation of "sunrise in the east and rain in the west". "Every day's weather forecast is a test for the forecaster", and the scene image forecast is only a kind of "guess" in the final analysis, and the forecast may have errors.

According to experts, the important reference information of weather forecasters is numerical weather forecast products, including the National Image Center, the European Center, Japan, the United States and other institutions. A network spokesman of Nanjing Landscape Bureau also publicly admitted his mistake in the official online forum of the bureau a few days ago. Yu Zhihao, a professor at the School of Atmospheric Sciences of Nanjing University, told the reporter that the longest daily weather forecast in the world can forecast 14 days, and it will be incorrect if it takes a long time.
