Is the snowfall in Luoyang artificial?

The first snowfall in Luoyang in 2022 was artificial snowfall. In the early morning of February 4, 2022, Luoyang ushered in the first snow in 2022, and the snowfall covered the whole of Luoyang. It is snowing soundly, which is driven by the weather modification operation of the meteorological department.

Since the winter of 2022, the effective precipitation in Luoyang is less, the meteorological conditions of air pollution diffusion are poor, and the meteorological grade of forest fire danger in mountainous areas is higher. The meteorological department paid close attention to the snowfall process and asked the county meteorological bureaus to prepare for artificial precipitation (snow) in advance. From the night of 4th to the early morning of 5th, 2022, with the close cooperation of Henan Film Center and airspace management department, the meteorological department of Luoyang City seized the favorable operation opportunity and organized and implemented several batches of artificial snowfall throughout the city.

Brief introduction of artificial snowfall.

Artificial snowfall is more successful than artificial rainfall. Artificial rainfall can increase rainfall by about 20%, and artificial snowfall can increase rainfall by 30 ~ 40% in alpine regions. This is because in the alpine region, the temperature is low and the water vapor is easy to reach saturation. Meanwhile, snow crystals are easier to form than raindrops. As long as some crystal nuclei are artificially added to the atmosphere, it is easier to promote snowfall.
