What role do weather conditions play in the formation of supercooled large drops?

Weather conditions significantly influence the formation of supercooled large drops, primarily through humidity and temperature. Supercooled large drops are liquid water droplets that exist at temperatures below freezing without crystallizing into ice. This phenomenon occurs in specific atmospheric conditions, where high humidity levels allow for the presence of larger liquid droplets.

Temperature is crucial here; as air temperatures drop, the likelihood of supercooling increases. When humidity is also high, it can lead to the formation of larger droplets that remain in a supercooled state due to the balance between droplet growth and freezing processes being disrupted.

In essence, both humidity and temperature create an environment conducive to the existence of these supercooled large drops, making their interaction critical in understanding their formation in weather patterns. This is why the correct answer emphasizes the combined influence of these two weather factors.
