Abstract

Abstract:

Based on the Chen-Weng heat exchange parameterized scheme, the average sensible heat flux from 1980 to 2017 in Qinghai Province was calculated using the observation data collected from 35 stations. Temporal and spatial characteristics of the sensible heat fluxes and their impact factors in Qinghai Province were determined using wavelet analysis, Mann-Kendall test, and Empirical Orthogonal Function. The result shows that the seasonal and annual average sensible heat fluxes have risen since 1980. The primary cycle of the annual average sensible heat flux was 28 a, and the secondary cycle was about 18 a. A high correlation between the seasonal and yearly average sensible heat flux with average ground-air temperature difference manifested. The annual average sensible heat flux increased from 2004 to 2017 due to a rise in the average ground-air temperature differences. The correlation of average wind speed with annual, spring, and autumn average sensible heat fluxes was high. The average yearly sensible heat flux decreased from 1980 to 2004 due to a decline in average wind speed. A prominent negative correlation between summer precipitation and sensible heat flux was identified. From the perspective of space, spring and annual average sensible heat fluxes expressed a prominent east-west difference and partly indicated a north-south variation in the autumn and winter.

Key words: sensible heat flux, Empirical Orthogonal Function, Mann-Kendall test, wavelet analysis, Qinghai Province
