Understanding Urban Heat Vulnerability and the need for Resilient Design Practice

Tuesday, May 22, 2018

The U.S. Southwest is rapidly becoming an urbanized region that is characterized by an intense urban heat island and summertime heat waves. At the city scale, high levels of urbanization in addition to local rising surface temperatures can affect the quality of life for several areas across residential communities, public and commercial spaces, etc. Heat within cities arises from different ways in which the built environment impacts energy exchange between the surface and atmosphere. This relationship causes unevenly distributed heat patterns across urban areas and some places tend to be hotter than others. Implementing green infrastructure shows promise to enhance the resiliency of urban areas (Benedict and McMahon, 2012). However, in several situations, the lack and disproportionality of green spaces withinin low-income, marginalized communities may further increase the vulnerability to heat and augment stress to communities that are already considered to be at a greater risk to heat (Read More).

May 2018 SW Climate Outlook - May Climate Summary

Monday, May 21, 2018

After a warm and dry winter (detailed in past issues of the SW Climate Outlook), drought, fire, and poor air quality (dust and pollen) are growing concerns as spring turns to summer. In May, warm temperatures (Fig.1), including triple-digit highs (Fig. 2), are increasingly common, while average precipitation is among the lowest monthly totals for the region (Fig. 3), and additional precipitation is unlikely. At the same time, the winds are picking up due to seasonal transitional conditions (Fig. 4), further increasing fire risk (Figs. 6a-b) and impacting air quality and public safety (e.g. dust storms).

Southwest Climate Outlook May 2018 - Climate Summary

Thursday, May 17, 2018

Precipitation and Temperature: The Southwest was characterized by below-average precipitation in April, ranging locally from record driest to near average (Fig. 1a). Temperatures were mostly above average for yet another month, with record-warm conditions along the eastern third of Arizona and the edge of western New Mexico, but also with a band of average to below-average temperatures on the eastern edge of New Mexico (Fig. 1b).
