WebHeat and internal energy. Heat is the energy in transit whenever temperature differences exist. The internal energy is equal to the sum of internal kinetic energy due to molecular motion and internal potential energy due to molecular attractive forces. A hot body has more internal energy than an identical cold body. WebIn particular, to promote the study of the drivers, and following the work of Sen Gupta et al. , we added the mean sea level pressure, the latent heat, the sensible heat, the incoming solar radiation, and the wind speed at 10 m. In addition, air temperature at 2 m is also available to promote studies on the relationship between MHWs and land ...
