Heat wave risk and impact assessment

Abstract:

Under the climate change, heat waves seriously affect the productivity and daily life of human beings. Therefore, they bring great risks and uncertainties for the further development of countries in the One Belt and One Road (OBOR) region. In this study, we used daily meteorological monitoring data to calculate the daily apparent temperature and annual heat wave dataset for 1989–2018 in the OBOR region. We studied their spatiotemporal distribution patterns. Additionally, multi-source data were used to assess heat wave risk in the OBOR region. The daily apparent temperature dataset and annual heat wave dataset for 1989–2018 in the OBOR region at 0.1◦ × 0.1◦ gridded resolution were calculated. Additionally, the frequency, duration and intensity of heat waves have been confirmed to increase continuously. The high heat wave risk areas are distributed in eastern China, northern South Asia and some cities. Heat wave risk in most areas along the OBOR route is relatively high.
