The conductive heat flow is always positive; at 08h00 the conductive heat flow (G) becomes negative. The
sensible heat flow (H) is negative, and at 06h00 equal to 0W/m2. As reported [8], "the radiative cooling fast than the
decrease in air temperature plainly visible the role of the sensible heat flow in the warming of the atmosphere." This
is probably connected to the strong daytime trapping of heat with radiation in the open street oriented North East-
South West. The sensible heat flow starts later in the morning and remain low with a big extant from 08h00 to
04h00. The results suggest that the heat stored in urban areas began to be returned to the atmosphere in the afternoon
when the energy balance is higher, reducing the heat storage in the soil and maintaining the conductive heat flow
positive and make the sensible heat flow negative. The differences in extent between the peak values of three flows:
energy balance (Rn), latent heat flow (LvE) and conductive heat flow (G) refer to the profiles of three morning
flows, at 14h00 the energy balance records 760W/m2, the latent heat flow (LvE) equal to 670W/m2 and the
conductive heat flow (G) stores 90W/m2. The latent heat flow dominated the energy balance throughout the day,
because of high evaporation in the street oriented North East-South West.
