The hurricane name is running out. What emergency measures do relevant departments have?

Recently, there is a hot topic in meteorology that everyone is talking about, that is, the name of hurricane is running out. If the names of hurricanes are used up, then hurricanes can only be named with Greek letters. In fact, the naming of hurricanes is very particular. Before 1950s, the naming of hurricanes was probably to name a number according to the chronological order of year and year, but this naming was very inconvenient and error-prone.

Therefore, after the 1950s, hurricanes began to be directly named. Each hurricane name is unique and easy to identify, mainly for the convenience of communication and information transmission. Moreover, not every weather station can be named, and it needs the unanimous consent of all the representatives of the World Meteorological Organization. Therefore, naming hurricanes is very particular.

The World Meteorological Organization has a naming table, which circulates every six years, and each Atlantic hurricane season is given 2 1 name. That is, in these six years, there are always 2 1 names that can be used according to different sea areas, and after the seventh year, we will start from scratch.

In the meantime, if the damage caused by the hurricane is particularly serious, then the name of the hurricane will be discarded forever after being used once, and then a new one will be found to fill it. Since the beginning of naming hurricanes directly, more than 90 names have been abandoned. If there are too many hurricanes in six years and the names of 2 1 are all used up, the Greek alphabet will be used. There are 24 Greek letters in all, and nothing unexpected will be enough. I hope there won't be a day when Greek letters run out.

However, the imminent exhaustion of hurricane names also shows that the climate problems caused by global warming have become very serious, and extreme weather has become frequent, which rarely happened before. Because the physical process of hurricanes, typhoons and tropical cyclones is that the sea level temperature rises, the rising hot air meets the cold air above, forming airflow circulation, and coupled with the geostrophic deviation of the earth's rotation, forming a large cyclone. Now global warming has greatly increased the probability of cyclone formation.
