Comments Off on How corn sweat is making this weeks heat wave even worse

Right now, there is one burning question on your mind, and I know it’s “What the heck is corn sweat?” The week’s extreme heat wave is blistering the middle section of the United States, where excess moisture from corn fields will evaporate and add an unwanted boost of humidity (called ‘corn sweat’) to the already uncomfortable levels. With temperatures expected to rise up to 20 degrees Fahrenheit above average in some places, meteorology experts say the phenomenon will happen more often as global warming worsens. The U.S. is in the midst of a severe heat wave , and it’s hitting the central and eastern parts of the country especially hard. The proverbial ‘they’ are famous for saying “It’s not the heat; it’s the humidity,” and in this case, it’s the darned truth. Scorching temps are plaguing most of the country this week, with the heat index rocketing into triple digits. Warm, moist air blowing in from the Gulf of Mexico combines with the corn sweat phenomenon to create a particularly miserable cocktail of heat and humidity in the Midwest, which is reflected in the heat index of what forecasters say will be the hottest summer on record.

Meteorologists have predicted that the next few decades will see this weather trend increase in severity and expand to impact even more areas, elevating the public health concerns associated with heat waves. Extreme heat is already one of the leading causes of weather-related deaths, particularly among the elderly and homeless populations, and the death tolls are likely to rise as the temperatures continue to soar.

Nobody needs a news report to know that summer is hot, but we’re in the midst of a particular scorcher. Scientists like to create visualizations to convey the full impact of natural phenomenon, such as heat waves, and this one from the National Oceanic and Atmospheric Administration (NOAA) reveals—in bright, flaming hues—what may be in store for the continental United States this week. The heat map was created using predicted high temperatures across the country , painting one toasty picture for the days ahead. Data from NOAA’s HRRR Model was compiled to create a map that shows the predicted high temperatures on July 18, 2016 at 5 p.m. EDT. The map is essentially a snapshot of the dawn of the  heat wave that is expected to last through the week. The heat wave is expected to be severe, as a “heat dome” created by a high pressure ridge and extreme temperatures will trap and intensify heat in several places across the U.S. Related: Lethal extreme heat and wildfires scorch the American Southwest The forecast calls for heat index values to reach 110 degrees or higher in some areas of the country. The National Weather Service issued heat alerts for more than a dozen cities in light of the soaring temps . A quick glance at this brightly colored heat map is slightly terrifying, but a slightly longer gaze will allow enough time for the realization that this is only the beginning, and there is a great deal of summer left to endure before temperatures will ease back to more comfortable levels.

When the developers of the popular OpenSignal Android app analyzed some of the data they’d gathered from their users, they were in for a surprise. They realized that the temperature sensors meant to keep the phones’ batteries from overheating could be used to predict the weather outside. The app doesn’t work on an individual level, instead it gathers data from a large number of users to estimate daily temperatures within 1.5 degrees Celsius.
