The La Niña phenomenon continues to escalate, will extreme cold weather occur?

September can be said to be still in the stage of autumn, but winter is not far away from us. From the perspective of global warming, there may still be many extreme weather conditions in the winter of 2020. The key is extremely cold temperatures. Of course, because my country is so large, there may be more extreme weather conditions in the region.

It is unlikely that a large-scale severe weather pattern will occur, and now that this year’s La Niña phenomenon has been officially announced, climate diversity in the winter of 2020 will definitely occur. This is also a new weather phenomenon following this year’s El Niño conditions. Under the influence of global warming, it is actually quite normal for extreme weather conditions to occur, that is, they will occur. For example, in summer, we have seen extreme high temperatures, droughts and other problems. Extreme cold weather conditions may still occur in winter, which is normal.

At the same time, the La Niña phenomenon itself may also have a significant impact on my country, so people have also been reacting recently. Will the La Niña phenomenon cause cold or hot weather in my country? There is really no way to answer this, we can only look at the development trend. As it happens, the discovery of the current La Niña phenomenon is still relatively clear. NOAA announced that after the La Niña phenomenon occurs, there is a 75% chance that it will last throughout the winter, so the impact on winter is likely to exist. Unless this is a temporary La Niña phenomenon, it will not be harmful if it disappears. However, judging from the current situation, the La Niña phenomenon may not disappear so quickly. The current Nio3.4 index is almost close to -0.6 degrees, so the continued development trend is very strong.

If this persists, then winter temperatures are mainly affected by the two basic natural climate conditions of global warming and La Niña. Combined with issues such as strong cold air, the climate will undoubtedly become extreme. Situations will occur. In fact, even if there is no La Niña phenomenon, extreme weather conditions are still likely to occur in winter.
