Protective forests protect people in mountains from natural hazards , but their capacity to do so might be jeopardized by natural disturbances 🌬 🐞 🔥 We've mapped this risk across the Alps in our new paper: https://lnkd.in/eT_hxFyr We used a combination Landsat and GEDI 🛰 to assess the probability of wind, bark beetle, and fire disturbances, as well as post-disturbance forest structure. 🌲 Surprisingly, a lot of forests (>40%) retained a sufficient structure to provide protection from natural hazards even after a disturbance (especially wind and bark beetle). You can check out our maps of disturbance hazard, vulnerability, and risk here: https://https://lnkd.in/eR-chMPr

Continue Day5 of #30daymapchallenge with our story of tropical cyclones. I'm always impressed by the extensive data resources available in Australia. The tropical cyclone database from the Bureau of Meteorology (BOM) includes thousands of records on tropical cyclones and low-pressure systems, making it an invaluable resource for public education and scientific research. The map I’m sharing today illustrates the paths of over 1,000 tropical cyclones documented in this database. One journey I highlighted is AU190707_01U, the first entry, which records the path of an unnamed cyclone that made landfall in Cooktown on January 19, 1907. This cyclone caused extensive damage—destroying three churches, two schools, four halls, three hotels, several shops, and numerous homes—and tragically claimed nine lives. This data provides powerful insights into the impact of past cyclones and helps us better understand these extreme weather events.

Reef fish community mean body size decreases in warmer waters and varies with trophic composition Mean reef fish body size decreases towards warmer waters By analysing ~15,000 coastal-reef fish surveys across a 15°C spatial sea surface temperature (SST) gradient, we found that the mean length of fish in communities decreased by ~5% for each 1°C temperature increase across space, or 50% decrease in mean length from 14 to 29°C mean annual SST. https://lnkd.in/gCf2iqeP

This #mesonet image posted by #NWS #NYC office yesterday of wind and temperatures at 12:30 PM illustrates the extent to which a #seabreeze penetrated inland over the 5 boroughs. The purple line I added shows a sharp contrast between #heatindex in the upper-70s to the south and east vs mid-upper 80s north and west. Wind vectors are notably stronger south of the boundary as well. It is worth noting that parts of southern and eastern #Brooklyn and #Queens do have more tree cover which helps lower temps also but the primary effect driving this stark difference is that sea breeze. Sea breezes are expected to form today and tomorrow as well, and it will be interesting to see how far inland they can push. How do sea breezes (a type of mesoscale circulation) form? They are driven by surface temperature differentials between the ocean and land, and require the absence of synoptic (larger scale like a cold front or low pressure) scale wind drivers, which we have with this #heatdome in place. On hot days, a thermal low forms over land, as hot air rises up, it induces cooler air from the ocean surface to move in and balance the thermal low. The stronger the thermal gradient, the stronger the circulation (temp differentials now are ~20°F between land and sea surface here), but you do need a minimum fetch (unobstructed stretch) over water to initiate the effect which is why you don't see the sea breeze over #StatenIsland and the #Bronx #heatwave #nycweather #newyorkcityweather #meterology

Your home is your sanctuary, but it’s also your first line of defense against the unpredictable whims of Mother Nature ☂️❄️☀️ Whether it’s scorching sun, torrential rain, or bone-chilling winds, weatherproofing your home is essential for comfort, energy efficiency, and maintaining the longevity of your property. In our latest blog post, we'll explore some tips that will help you weatherproof your home like a pro - read here ➡️ https://hubs.ly/Q02dZ7Mf0

Most birds are mostly waterproof. Their feathers, aided by oil from preen glands, keep them pretty watertight. So why do birds avoid flying during rainstorms? It may have more to do with the air than with the water. Rainstorms tend to occur when atmospheric pressure is low. Air in a low-pressure system is less dense. But it’s dense air that gives birds the aerodynamic lift they need to take wing. Falling rain and high humidity make air even less dense. Many birds perch and wait out a storm. Afterward, birds once again take to the skies. https://lnkd.in/dGtTeKxZ
