Question

It is 35°C at sea level. The environmental lapse rate between sea level and 2100 meters is 6.85 °C/1000m. The environmental lapse
rate between 2100 meters and 3500 meters is 11"C/1000m. The normal lapse rate exists above 3500 meters. What will the
temperature be at 9000 meters? Calculate your answer to one decimal point.

Answer 1

Based on the various lapse rates, the temperature at 9,000 meters will be 30.53°C.

Temperature at 2,100 meters

= Sea level temperature - Lapse rate x Difference in Depth from last lapse rate

= 35 - (6.85 / 1,000 x 2,100)

= 20.62°C

Temperature at 3,500 meters

= 20.62 - (11 / 1,000 x (3,500 - 2,100))

= 20.62 - (11/1,000 x 1,400)

= 5.22° C

Temperature at 9,000 meters

= Temperature at 3,500 meters - Normal lapse rate x Difference from last lapse rate

Normal lapse rate = 6.5 ° C / 1,000 meters

= 5.22 - ( 6.5 / 1,000 x (9,000 - 3,500))

= 5.22 - ( 6.5 x 5.5)

= -30.53° C

In conclusion, the temperature at 9,000m will be -30.53°C.
