Summary:

The diurnal variation in the surface thermodynamic fields over the island of Hawaii is presented, for the first time, as this paper is a continuation of the work that was done by Chen and Nash in 1994. Since the surface of airflow and rainfall occurrence are closely linked to the diurnal heating cycle as was discovered by these two scientists, the climatology of diurnal variation in thermodynamic fields that were based on the surface data that was collected from 50 Portable Automated Mesonet surface stations during the Hawaiian Rainband Project that was on the island of Hawaii from 11 July - 24 August 1990, will be presented. Since the authors of this paper hoped to discover why the onset of downslope flow in the evening occurs in the windward lowland west of Hilo, whereas the onset of upslope flow in the morning occurs on the windward upper slopes, the thermal contrasts between the windward slopes and the adjacent areas during the morning and evening transition periods was examined during this study. This was done in an effort to assess whether or not the thermal forcing is important for the evolution of the island-induced wind regimes on the windward side of the island.
