The difference between using how and what to ask about the weather

Differences in inquiry methods and expressions.

1. Differences in inquiry methods: use "how" to ask about weather conditions, and use "what" to ask about specific meteorological conditions. "Howistheweathertoday?" (What is the weather today?) asks about the overall weather conditions, and "Whatisthetemperaturetoday?" (What is the temperature today?) asks about the specific temperature.

2. Differences in expressions: When using "how", it will be followed by an adjective or adverb to describe the characteristics or state of the weather. "How hot is it today?" (How hot is it today?) or "How windy is it outside?" (How windy is it outside?). When "what" is used, it is followed by a noun to refer to a specific meteorological condition. "What is the humidity level?" or "What is the precipitation forecast?"
