Kelvin–Helmholtz instability (hereafter KH) waves and their microphysical impacts are well documented within falling precipitation, but observations of KH waves at cloud top are extremely scarce and their impacts on clouds and precipitation have yet to be characterized. This paper presents the first known study of cloud-top KH waves producing snowfall with observations of increased snowfall rates at the surface. The falling snow removed ∼80% of the SLW content from the underlying cloud and led to a twofold increase in surface liquid equivalent snowfall rate from 0.6 to 1.3 mm h −1. Relatively weaker updrafts of 0.5–1.5 m s −1 beneath the fluctus and partially overlapping the dendritic growth zone were associated with steep gradients in reflectivity of −5 to 20 dB Z e in as little as 500-m depths due to rapid growth of pristine planar ice crystals. A distinct fluctus region appeared as a wave-breaking cloud top where the fastest updraft was observed to exceed 5 m s −1. KH wavelengths of 1.5 km consisted of ∼750-m-wide up- and downdrafts. In situ cloud probes and surface disdrometer measurements are used to quantify the impact of the snow plume on the composition of an underlying supercooled liquid water (SLW) cloud and the snowfall observed at the surface. Airborne transects of cloud radar aligned with range height indicator scans from ground-based precipitation radar track the progression and intensity of the KH wave kinetics and precipitation. Here, we present detailed observations of cloud-top KH waves that produced a snow plume that extended to the surface. The market won't be overvalued after this process is over," Zandi says.Kelvin–Helmholtz instability (KH) waves have been broadly shown to affect the growth of hydrometeors within a region of falling precipitation, but formation and growth from KH waves at cloud top needs further attention. "Before prices began to decline, we were overvalued by around 25%. When it's all said and done, Moody's Analytics chief economist Mark Zandi thinks this ongoing housing correction will push national housing fundamentals back in line with historic norms. home prices during the Pandemic Housing Boom has simply put monthly payments beyond what many would-be borrowers can afford. Spiked mortgage rates coupled with a historic 43% jump in U.S. Why are home prices already starting to roll over? It boils down to what Fortune calls pressurized affordability. (You can find their forecast for 322 markets here). Meanwhile in Chicago, a relatively tame market during the boom, it expects a home price decline of less than 3.6%. In bubbly markets like Boise and Nashville, Moody's forecasts a decline of around 20%. Regionally, researchers acknowledge that shifts in home prices vary significantly by market. house prices," they're talking about a national aggregate. However, if a recession hits, Moody's Analytics would expect a bigger 15% to 20% peak-to-trough decline. home price decline, with prices bottoming out in late 2025. Just how far will home prices fall? It depends on who you ask. That’s the biggest home equity drop ($1.3 trillion) ever recorded, and the biggest percentage drop since 2009. home equity, as reported on Friday by Black Knight. Just look at the 7.6% decline in third quarter U.S. It’s also likely well below the actual drop. home prices had fallen 1.3% from their June 2022 peak. “Folks responding to that with almost PTSD, and they pull back much more quickly,” Kelman says.Īs of August, the lagged Case-Shiller Index showed that U.S. Once the market shifted, they wanted to get out first. Knowing that home prices can indeed fall, Kelman says, is why builders and flippers started cutting prices faster this time around. home prices to fall a staggering 27% from 2006 to 2012. That “religion” of course came crashing down after the bursting housing bubble caused U.S. My parents believed that it was literally inconceivable for prices to go down,” Redfin CEO Glenn Kelman tells Fortune. “I think that the religion people had from 1946 to 2008, that housing prices always go up, is dead.
