What you need to know about this month’s total solar eclipse

  What you need to know about this month’s total solar eclipse Mark your calendar: Aug. 21 is the Great American Eclipse. That’s when people in a 70-mile path from Oregon to South Carolina will have the eerie midday experience of seeing the sun blotted out by the moon. Even if you’re outside the main path, you can still get the treat of a partial eclipse. (Find out the exact eclipse time for your area here, and we have separate audio stories above and below for those in the path of the total or partial eclipse, respectively.) Also, we want your eclipse plans, stories and photos. “Totality begins at about 10:15 [a.m.

In the hopes of learning more about how tornadoes form, researchers are flying drones into the eye of the storm, collecting promising weather data that could possibly help forecasters predict the destructive path of these systems.

The astrophysics of the eclipse are known, so for space watchers it will be a time to relax and partake in the strange beauty of day gone suddenly dark. For the atmospheric scientist however, the eclipse provides a shining opportunity to directly study how the sun influences weather patterns by heating the atmosphere. To that end, a team of researchers from Oklahoma State University and the University of Nebraska is going to spend Monday tracking changes in the atmosphere in the path of the eclipse. And to get just how the eclipse changes the weather in the low sky, the team will fly drones during the totality.

What time is the solar eclipse where I live?

  What time is the solar eclipse where I live? You'll need perfect timing to catch the exact moment the moon blocks the sun in your city. The total solar eclipse on Aug. 21 lasts less than a minute in some places, while a partial eclipse can be visible for an hour or more.

In addition to the radars, lasers and other electronic instruments, Knupp's team will launch weather balloons into the stratosphere. He also is aware of forecasts of huge crowds and potentially transcontinental traffic gridlock along the path of the eclipse .

Researchers aboard a Gulfstream V will study the sun’s rarely-seen outer atmosphere. The Gulfstream V operated by the National Center for Atmospheric Research will spend four minutes under totality by flying along the eclipse path .

This flight is part of the broader “Collaboration Leading Operational Unmanned Development for Meteorology and Atmospheric Physics” (CLOUD MAP) project, where four universities are trying to figure out how to use drones to better study weather. Drones are ideal because they can fly above towers and below where manned aircraft and balloons operate. It’s this lower atmospheric boundary layer that the drones are built to study.

“There’s an impact during what we call the diurnal cycle, the night-day boundary, the sun comes out, starts heating up the ground, and that’s where a lot of our unstable weather phenomena starts to form,” says Jamey Jacob, a professor of Mechanical and Aerospace Engineering at Oklahoma State University. “The sun comes out, starts to heat the ground up, moist bubbles of air detach from the air as they get hot and go up and form thunderstorms, tornadoes, all kinds of things."

Most eclipse flights, which have become fairly common each time there is a total eclipse , depart early, make their way into the eclipse path and fly with it, waiting for the shadow to catch up.

The Eclipse of the Century may also turn into the Science Experiments of the Century. Guinan will be in Grand Island, Nebraska, to fly cameras on drones and make high-speed videos of the shadow bands as the eclipse shadow moves rapidly What will the weather be for solar eclipse ? News.

The eclipse offers a rare moment to observe the change against the backdrop of the day, to see how a sudden absence of that direct, solar heat changes the air and in turn changes the weather. For the measurements, the drones are equipped with sensors to collect temperature, humidity, and pressure readings, as well as special ultrasonic sensors, designed to measure the wind.

“It may sound relatively simple but essentially you take away that radiation, that heat in a certain area,” says Jacob, “it starts to cool down, as it cools down you essentially get a giant sucking effect from the hot air around and into this colder region.”

By the end of Monday, the drones should know if the eclipse sucks, though it will take more time to thoroughly analyze all the data collected. To match the drone flights to the sequence of the eclipse, they are equipped with light sensors, and some drones will have visual light and infrared cameras to see if they can stop any interesting phenomena. And the drones will fly, not just during the totality of the eclipse, but throughout the day, comparing readings from the drones to stations on the ground to balloons sent into the sky, building a complete picture of what a little solar darkness means for the weather that follows.

“Nothing,” says Jacob, “could be cooler or geekier.”
