Rain, snow, ice and frost are all different physical phenomena in nature. In which season do the above phenomena appear all year round?

Both rain and dew appear in summer, and dew mainly appears in summer morning.

Ice, snow and frost all appear in winter. In the north, frost usually appears in the morning after the first frost (24 solar terms), while ice freezes when the temperature is below 0℃. The snow condition is worse. Of course, the premise is that the temperature is lower than 0℃
