The weather component that Jade is describing is Air temperature.
Here's why:
1. When Jade mentions "It drops as you go higher," she is referring to the fact that air temperature decreases as altitude increases. This is known as the lapse rate in the atmosphere.
2. Jade's statement "It is usually higher on summer days" aligns with the general understanding that air temperatures are typically warmer during summer due to increased solar radiation and longer daylight hours.
3. Lastly, Jade's comment about the low and high temperatures being shown on a weather map indicates that she is talking about air temperature as it is a fundamental aspect of weather forecasting and is often depicted using different color gradients on weather maps to represent temperature variations.
In summary, based on the clues provided by Jade, the weather component she is describing corresponds to Air temperature.
