Question
uppose you wake up on a Summer morning and notice that the outside temperature is relatively cool. However, your local TV meteorologist says that the atmosphere is currently very unstable and severe weather is likely in the afternoon. As the day progresses you notice that the temperature increases and, sure enough, severe thunderstorms form. How were thunderstorms able to occur?
Question 7 options:
The low-level moisture was increased thus lowering the surface air parcel's LCL.
Surface heating removed all of the CIN that was present in the morning.
Surface heating decreased the temperature just above the surface thus removing all of the CIN that was present in the morning.
Wind profiles became more favorable for severe thunderstorms as the day progressed.

Explanation / Answer
As the day progresses you notice that the temperature increases and, sure enough, severe thunderstorms Thunderstorms able to occur as the surface heating removed all of the CIN that was present in the morning. Because Convective inhibition or CIN or CINH is a numerical measure in meteorology which indicates the amount of energy that will prevent an air parcel to rise from the surface to the level of free convection.
