- 3. The data below shows the environmental temperature at different height: Altitude (m) 0 50 Temperature (°C) 24.00 23.75 100 23.50 150 200 23.25 23.00 Above 200 m, the ambient temperature increases at the rate of +20 °C km*1. (a) A 100-m tall stack emits a plume whose temperature is 24.50°C. Using graphical method and with justification, predict the maximum mixing height of the plume. (b) Describe the type of plume emitted under the conditions mentioned in 3(a).2. If the sun's output of solar radiation increased by 20%, how would this impact the temperature of Earth's mantle? Why?If air temperature is 7 5 degrees at sea level, what is the temperature at the top of Pike's Peak ( elevation 1 4 , 0 0 0 ft ) ?
- 3. Calculate the geostrophic wind speed in meters per second for a geopotential height gradient of 102 m per 1000 km. Compare this value with the four gradient wind speeds for the same height gradient and a radius of curvature of 500 km. Identify the anomalous and normal cyclones and anticyclones. Assume f = 10-4 s¯¹. [~ Holton 3.4] -1 S15. The consensus view among climate scientists is that the above increase in global temperature is due to an increase in atmospheric CO2 caused by human emissions. The below plot is a record of the increase in CO2 measured since 1960. A) What was the atmospheric CO2 concentration in 1960? B) How about in 2020? C) What do you think causes the annual variations?
