There were air temperature differences between the places at the edge of canals and the places without canals at 14:00 of August 15. However, the cooling effect of the canals was appeared not clearly on the distribution of air temperature and water vapor pressure. The maximum temperature difference between the canal surface and the road surface was observed 32.3°C in the daytime.
