What is the meaning of fallout zone

Meteorological forecasting is a science, but the spatial and temporal distribution of rainfall and often uneven. Here surfaces the traditional dilemma of storm forecasting: the fallout zone. The so-called drop zone forecasting refers to the regional forecasting of the occurrence of catastrophic weather and its secondary disasters, and when heavy rainfall is frequent, the drop zones tend to overlap.

In this way, in heavy rainfall forecasting, there will be three kinds of weather stations in the relevant area, one is the weather station that forecasted and appeared heavy rainfall, the second is the station of the empty report, and the third is the station of the omission of the report.

Guangzhou south, north and west of the rain fell, but only Guangzhou is very gentle, fearing that the rain will be a little bit more noisy to the people of Guangzhou. In fact, this mysterious boundary is not a fictional mana formed and can be defended, but a topic in meteorological science - the drop zone.
