The Role of Weather in the Water Cycle and Its Importance to Life on Earth Weather plays a fundamental role in the water cycle, a continuous process that is crucial for sustaining life on Earth. The water cycle encompasses various stages, including evaporation, condensation, precipitation,… #WEather >>> Read more

The #US is facing an intense #heatwave, with high temperatures impacting several regions. #HeatIndex readings are expected to reach dangerous levels, posing a risk to many. A #HeatDome forms when a high-pressure system develops in the upper atmosphere, causing the air below to sink and compress.

In the past few years, we have seen most of the weather forecasting agencies are publishing Feels like Temperature. Would you happen to know how it is calculated? Despite its less-than-scientific sounding name, “feels like” is derived from this carefully designed equation: AT = Ta + 0.33E - 0.7WS - 4 In that equation “AT” stands for “apparent temperature” (the “feels like” reading). “Ta” is the ambient temperature reading, the baseline temperature measure. “E” indicates a specific measure of humidity called “water vapour pressure” which is multiplied by 0.33, while “WS” is the current wind speed multiplied by 0.7.

Earth just had its WARMERST July on record 🌡️🥵 This highlights the urgent need for sustainable water management. As temperatures soar, the demand for water increases, putting immense pressure on aging infrastructure. 👉 Read more: https://lnkd.in/gDzz4K9K Effective leak detection technologies, like EFAS’s Global AI Leak Locator (GAILL), are more crucial than ever. By identifying and repairing leaks promptly, water utilities can minimize water loss, ensuring that every drop is conserved. This helps in maintaining the integrity of the water supply during extreme weather conditions. Proactive leak detection is a vital step in adapting to our changing climate and securing a sustainable future for all. 💧🐾 Learn about our AI-powered GAILL: https://lnkd.in/gZtuCPQJ --------- EFAS Technologies - AI-powered Utility Leak Detection ☎ +1 888-800-3801  📧 [email protected]  🌍 https://efastec.com #EFAS #GAILL #AIpowered #LeakDetection #ClimateChange #WaterScarcity #WaterSustainability #LetsMakeWaves

In post after post, Alpha Lo shows how the water cycle drives climate, and how our actions (meaning, how we manage land and vegetation) impact the water cycle. We can--and need to--do so much better!

While wintertime precipitation is welcomed with open arms in California, intense atmospheric rivers bring negative impacts such as flooding, landslides, runoff, and more. Aa higher proportion of our annual rainfall will continue to come during these events, we need to adapt to better mitigate these hazards

The so often forgotten water cycle. Again, simple solutions that could have a big impact. Keep and regenerate wetlands, seasonally wet low areas and riparian areas. Keep them vegetated and they will give wildlife haven, fix carbon, clean surface water runoff and help regenerate groundwater. For urban dwellers, build swales and rain gardens instead of planting useless shallow rooted grass. Small and simple steps for the greater good. If you choose to do one of these things this summer, what will it be? Or something else entirely?

#What is “Temperature Feels like”? In the summer, the feels-like temperature is also called the heat index. The "feels like" temperature, also called apparent temperature, is a measurement of how hot or cold the air feels when combined with other environmental factors like relative humidity, wind speed, and dew point. For example, wind can remove the natural layer of warmer air around your body that helps to insulate you from cooler air. This is called wind chill. The “feels like”, or apparent, temperature is what a regular person would experience when outside, in the shade, and dressed for the weather, says Bureau of Meteorology forecaster Pieter Claassen. “The apparent temperature will take into account differences in conditions that … will affect how that temperature feels to people,” he says. This allows meteorologists to get an accurate reading of air temperature in the shade. But it “doesn’t really account for the subtle differences in how conditions feel day to day”, Claassen says. To provide a fuller picture, “feels like” is calculated using air temperature along with factors including wind and humidity. More specifically, despite its less-than-scientific sounding name, “feels like” is derived from this carefully designed equation: AT = Ta + 0.33E - 0.7WS - 4 In that equation “AT” stands for “apparent temperature” (the “feels like” reading). “Ta” is the ambient temperature reading, the baseline temperature measure. “E” indicates a specific measure of humidity called “water vapor pressure” which is multiplied by 0.33, “WS” is the current wind speed multiplied by 0.7. And then they take 4 off at the end for good measure, which Claassen explains is part of the calibrations done when Australian researcher Robert Steadman first designed the equation. And then they take 4 off at the end for good measure, which Claassen explains is part of the calibrations done when Australian researcher Robert Steadman first designed the equation. “The equation is to give us a specific reading, but the general rule of thumb is: the windier it is, the cooler it will feel, and the more humid it is, the warmer it will feel,” Claassen says. “So it’s a balance of those two factors, which takes the actual temperature and turns it into a ‘feels like’ temperature.”

🌍 Uncovering the Impact of Flooding on CO2 Emissions 🌊 Did you know we investigated the relationship between floods, atmospheric factors, and CO2 emissions from the closed mine shafts in Kerkrade? The 2021 summer flood in Europe provided a unique backdrop, prompting us to understand the impact of elevated water levels on CO2 emissions. 💡🌊 Our investigation aimed to shed light on the potential risk of CO2 leakages from historic mine shafts in Kerkrade, building on past research highlighting atmospheric pressure and mine water levels as contributing factors. 🌧️🔬 The study revealed intriguing findings—during and post-flood, CO2 leakages experienced a notable increase from the mine shafts in Kerkrade. Of particular interest was the intensified impact of atmospheric pressure during the flood, leaving a lasting imprint on CO2 concentrations. Beyond the CO2 narrative, our dataset led to the development of a robust flood prediction model. Leveraging Random Forest classification and careful hyperparameter optimization, the model showcased impressive accuracy. While ground- and mine water levels played significant roles, the model demonstrated reliability even without them, hinting at a future where floods could be forecasted accurately 📈🌟   #environmentalresearch #floodanalysis #co2emissions #datadriveninsights #floodpredictions #sustainablescience

“Changing Winter Warm Spells on Snow Ablation Over Western North America”   The consequences of extreme maximum winter temperatures (aka Winter Warm Spells) include snowpack ablation and thus, the long-termsecurity of mountain water resources.  Potential impacts include those to stored M&I/Ag water supplies, hydropower generation, instream flows, riparian/instream habitat, downstream water quality, etc..   Winter Warm Spells are defined as a winter period (December to February, DJF) of at least 3 consecutive days with daily maximum temperature anomaly above the 90th percentile (using a moving-average of 15 days between 2001 and 2013).   In a recent study, Winter Warm Spells were calculated for every 4-km grid cell within an atmospheric model over western North America.   Results showed that, despite the relatively few days with ablation during Winter Warm Spells between December and February (about 0.6% or 0.6 days), those days produce almost half of snow winter ablation (49% or 16.5 mm).  Winter snow ablation, mostly composed of melt events (93.6%), is expected to increase under a warmer climate (88% increase in melt, from 19.8 to 48.9 mm), with significant differences across climatic regions.   As the study authors duly note, the challenges in representing mean temperature across large domains, and the effect of small-scale processes such as cold air pooling and snow-forest interactions, should be further investigated to improve land-surface models' predictability of winter ablation.   See Scaff et al.
