If we convert the specific humidity thresholds to dewpoint, here's a map showing the extent of summertime "mugginess", where the average dewpoint is 65°F+ (northern blue contour line). The southern blue contour line shows the region where the average summertime dewpoint is a soupy 72°F+.

I'm thrilled to share this paper that was just published today in Climatic Change on the effect of "seasonally muggy" conditions that exacerbate chronic heat and thermal discomfort in places like south Florida. doi.org/10.1007/s105... Lead author: @weatherkos.bsky.social

Nighttime land surface temperature and thermal discomfort in a seasonally muggy climate - Climatic Change

Globally, increasing air moisture can limit not only the human body’s ability to cool down, but also that of the Earth’s surface. This interaction, however, remains understudied—especially across subtropical-to-tropical regions that experience high levels of humidity. Here, we examine how air moisture influences nighttime land surface temperatures (LSTs), as well as what this interaction means for thermal comfort overnight. During summer months across seasonally muggy Southern Florida, during which time air moisture reaches the highest values of any place in the United States, we examine: 1) how air moisture, measured as specific humidity, varies with urbanicity and geography; 2) whether air moisture limits LST cooling at night; and 3) the implications of increased air moisture and nighttime LSTs for thermal comfort overnight. Based on data from 30 weather stations, we find that nighttime LST remains higher and closer to daytime highs in areas with increased specific humidity, highlighting a decreased surface cooling phenomenon in more humid areas. Both urban and coastal areas exhibit higher nighttime LSTs that are strongly related to thermal discomfort—also resulting in more time spent at or above critical thresholds for thermal discomfort overnight. This analysis therefore underscores the importance of heat mitigation and adaptation strategies that reduce LSTs and anthropogenic heat inputs in seasonally muggy climates in order to increase thermal comfort, especially near coastlines at lower latitudes.

I think I have a very limited understanding of how networking on blue sky works, outside of simple follows lol—apparently there are lists or communities you can join? And if so, how do I do it?!? Signed — an ignorant millennial

So how have groups like #MDPI and #Frontiers accomplished this incredible growth? "Dear prof. ___, we read your manuscript and were thoroughly aroused. We invite a preeminent like you to submit to our special issue on TOPICYOUDONTSTUDY." These issues are not so special... đź§µ 4/n

Looks like videos aren’t a thing on here just yet—but still fascinated with last week’s gulf low, which seems to be the southeast’s version of a nor’easter at this point. Incredible rainfall
