Interactive comment on “Diurnal variation of upper tropospheric humidity and its relations to convective activities over tropical Africa” by E. S. Chung et al

In the revised version, we emphasized new results from EOF analysis and Lagrangian approach. Following sentence is added in the abstract: “The EOF analysis indicated that these diurnal variations over the African continent seem to be closely related to continental-scale daytime solar heating and topography. On the other hand, advection effect on the diurnal variation appeared to be minor because of the similar patterns shown in both Eulerian and Lagrangian approach.”
