  text: Short-duration extreme rainfall events are the main trigger of flash and pluvial
    floods in cities. Depending on the local climate zone and urban fabric that affect
    meteorological variables such as air temperature, humidity, and aerosol concentration,
    the built environment can either intensify or reduce extreme rainfall intensity.
    This study examined how urbanization in a large metropolitan area characterized
    by open low-rise buildings, affected sub-daily extreme rainfall intensities over
    the period between 2000 and 2018. The research was conducted in the metropolitan
    region of Phoenix, Arizona, which is supported by a large and dense rain-gauge
    network (168 stations). The built area increased by 6% between 2001 and 2016 and
    the number of residences by 300,000. Over the study period, sub-daily extreme
    rainfall intensities intensified both in the urbanized area and in its rural surroundings
    but the intensification trend within the built area was considerably larger (3
    times larger). We calculated a negative trend in aerosol concentration (−0.005
    AOD y−1) but a positive trend in near-surface air temperature that was considerably
    larger in the urban areas (0.15 °C y−1) as compared to the rural counterpart (0.09
    °C y−1) for the period between 2005 and 2018. Although built surfaces and open
    low-rise buildings contributed to an increase in air temperature, they did not
    affect air humidity. Changes in rainfall extremes approximately follow the Clausius–Clapeyron
    relation within the urban area with an increase at a rate of 7% °C−1. These results
    demonstrate that the warming effect associated with a low-rise urban area can
    cause an intensification of sub-daily rainfall extremes that is significantly
    larger than in nearby rural areas.
