Phlerndip Posted July 1, 2017 Share Posted July 1, 2017 It is my understanding that Rays from the sun heat the surface of the Earth through radiation. The ground then heats the air through convection and conduction. Knowing this, How come in in the morning, around 10am, the air temperature can be higher than the ground temperature. This morning in Western NY, The surface temperature maps said the surface was 64 degrees, while the air temperature was 72 degrees. Can someone who knows more than me please explain why this happens? Thank you Link to comment Share on other sites More sharing options...
Hoosier Posted July 1, 2017 Share Posted July 1, 2017 The simple answer is that the ground is more efficient at heating during the day/cooling at night than the air. After sunrise, it takes some time for enough of the sun's energy to reverse the ground cooler/air warmer process that happened overnight. Link to comment Share on other sites More sharing options...

How can that happen if the grounds temperature is lower?Sent from my LGLS755 using Tapatalk Link to comment Share on other sites More sharing options...
Hoosier Posted July 1, 2017 Share Posted July 1, 2017 The ground starts out colder than the air just above it, but warms rapidly as morning progresses and becomes warmer than the air just above. Link to comment Share on other sites More sharing options...
dendrite Posted July 26, 2017 Share Posted July 26, 2017 Where are you getting these temp values from? The sfc (skin temp) shouldn't be that much colder than 2m at 10am this time of year with mostly sunny conditions. Link to comment Share on other sites More sharing options...
