Both a saturated and an unsaturated parcel, each with a temperature of 150C, are forced to rise from the surface to a height of 2 km. Which parcel will be warmest upon reaching 2km? a. the saturated parcel b. the unsaturated parcel c. the will both be the same - CORRECT ANSWER-the saturated parcel By examining either the sounding you chose in question 15 or the sounding you plotted and considering the LCL, how would typical afternoon heating affect cloud bases (assuming the moisture content of the air remained the same, i.e., the dew point temperature remained unchanged)? a. Cloud bases should lower because the atmosphere is warmer. b. Cloud bases should lower because the LCL would be lower c. Cloud bases should be higher because the LCL would be higher. - CORRECT ANSWER-Cloud bases should be higher because the LCL would be higher; If the temperature warmed but the dew point remained the same, there would be a greater difference between the two. As a result, a parcel would need be lifted higher before the temperature and dew point temperature equalled one another. Therefore, the cloud bases would be higher. Calculate the 1000-500 mb thickness if the height of the 1000mb surface is 185m and the height of the 500 mb surface is 5525m. - CORRECT ANSWER-534 dam; Thickness is calculated by subtracting the 1000mb height (185m) from the 500mb height (5525m). You then need to
