The weather forecast often reports that it will rain locally. What do you mean it will rain locally?

This question is very professional ~? Is it raining locally? This means that it will rain in some places. Do you remember when we were young, we always heard reports from forecasters? Is it raining locally? I have been entangled in the question of where the local area is, and it rains every day. ?

Let me tell you a little joke first: one day I went back to the village to see my aunt. After dinner, we chatted. We talked about the frequent rain during this period, which made it inconvenient to travel. My aunt came over and said, we have been living very well here. It only rained for four days. I listen to the weather forecast every day. There is a place called local. That place is terrible. It rains almost every day and never stops.

To put it bluntly, the weather forecast is not accurate. It rains in some areas and it doesn't rain in some areas.

Local area refers to the area that cannot be determined, and also refers to the area with small local area in the forecast area. For example, in summer, in the same city, there is rain in the south and no rain in the north, and the south is a local area of the city, which means that it is difficult to reach an accurate small area at present. ?

Generally speaking, the forecast of sunny and rainy weather refers to a range of forecast, refers to the forecast conclusion of a certain area, and is also a region for the rainfall cloud system. If the forecast area is wide, the rainfall cloud system cannot cover the whole forecast area, and there may be rain in some areas.

In the region, especially in summer, the area of convective clouds is generally much smaller, and it often rains in Tianhe, Panyu and even the Pearl River New Town. For the current weather forecasting technology, this small-scale local precipitation can only be seen from a large-scale situation, which is unstable and easy to cause convection. It is difficult to report this rainfall point in short-term forecast. When there is rain and it is impossible to predict the exact rain point, the short-term forecast will report that there is rain in the local area. Specific rain spots can only be supplemented by short-term monitoring products.

Of course, with the increase of monitoring stations, the monitoring network becomes more and more dense, and the improvement of monitoring data density can improve the accuracy of numerical model prediction, and the accuracy of numerical model prediction is also gradually improving.
