A low pressure system I believe.
The atmosphere prevents the sudden increase in temperature during the daylight hours. And during the night, it slows down the escape of heat into outer space. +++ It would be more accurate and more to the point to state that without the atmosphere there would be no climate!
...HEAT CAPACITY ... sooo easssyy
It keeps the temperature of our planet i.e. the Earth fairly steady. During daytime, the atmosphere prevents the sudden increase of temperature. During night time, it slows down the escape of heat into outer space. On the moon due to the absence of the atmosphere the temperature there ranges from -190 to 110 degrees.
A sudden change in Earth's atmosphere could be represented by phenomena like severe storms, hurricanes, tornadoes, or sudden temperature drops. These events can indicate rapid shifts in weather conditions and atmospheric pressure.
A sudden drop in temperature, an increase in wind speed, or darkening clouds could be signs that the weather is about to change for the worse, possibly indicating the arrival of a storm or other severe weather conditions.
The wind will increase and the temperature will drop. In addition, rain will usually fall along or near the front.
The sudden drop in air temperature is a stimulus.
A sudden drop in temperature, darkening clouds, and an increase in wind speed are signs that the weather may change for the worse at sea. These can signal an approaching storm or adverse weather conditions.
The sudden drop in air temperature is a stimulus.
Sudden increase or decrease in temperature Change in color or appearance of an object Shift in behavior or activity of living organisms
A sudden drop in temperature, an increase in wind speed, darkening clouds, or a sudden shift in wind direction can indicate that the weather may change for the worse. These signs are often associated with approaching storms or deteriorating weather conditions.
