Will it really be very cold this winter?

According to the forecast of the World Meteorological Organization, it will be particularly cold this winter.

Moreover, at the beginning of 1 1, the heavy snow and low temperature brought by a strong cold wave seem to indicate that this winter will be really cold.

However, it is uncertain whether it will really be particularly cold this winter.

I think so, for the following reasons.

1, the source of low temperature forecast this winter.

It will be cold this winter because of La Nina phenomenon caused by abnormal atmospheric circulation.

Whenever La Nina phenomenon appears, it will be accompanied by abnormal temperature in the Pacific Ocean.

In this way, it will affect the winter temperature in the northern hemisphere.

According to the analysis, whenever La Nina phenomenon appears, the probability of cold winter in the northern hemisphere will be greater.

Therefore, the World Meteorological Organization will predict that it will be very cold this winter.

2. Whether the forecast is reliable.

Since the appearance of La Nina phenomenon is not necessarily accompanied by the cold winter in the northern hemisphere, it is not clear whether this winter is really a cold winter.

3, the current situation.

165438+1At the beginning of October, there was heavy snowfall and cooling weather in the north.

However, from the end of June 165438+ to the beginning of February, the temperature rose, and even the temperature in many northern areas rose to zero.

Therefore, at least for now, there is no particularly cold phenomenon this winter.

However, this winter has just begun, and how the future situation develops is the key to whether this year is a cold winter.

So whether it will be particularly cold this winter needs further observation and analysis.
