What kind of weather do the three horizontal lines under the moon represent?

The three horizontal lines under the moon represent frost weather.

When the temperature drops to a certain level, the water vapor in the air will condense into solid ice crystals, forming the so-called frost. Frost refers to a weather phenomenon that forms under weather conditions with good visibility at night in clear, windless and breezy areas. In the early morning of autumn and winter, you can often see white spots on the ground. This is the appearance of frost flowers. Determine whether the terrain and airflow rise or fall in places where frost appears. The presence of frost means cooler temperatures and dry conditions.
