Researchers from Kyushu University in Japan give some new insights about geomagnetic storms that burn on the last day of solar.
Work focuses on storm activity in a region of land ionosphere Called e layer, sitting in upper space about 56 miles 75 miles (90 to 120 kilometers) above sea level.
“The sporadic e layer has not been studied during the storm because it shows unaffected Storel Storms“Studying the leader Huixin Liu said to a statement.
“But we want to see if something is strong as Mother geomagnetic storm No one is done in e layer, “Liu added.” What we find is very interesting. “
The content is more enhanced during the storm, the team was found; Thin patches of high advertisement of ionization – known as sporadic e layer, or sporadic es for short-suddenly showing ionosphere.
To gather data in events, the team depends on a combination of sources from space and the ground.
Using the combined US-Taiwanese cosmic-2 SATELLITE Network, as well as 37 land-based radios called ionosode, the team gathers a large weather information and after a global map of the sporadic e layer activity.
“This large amount of data is critical for two found the presence of sporadic es and tracking where they have been passing through time,” says Liu.
“In our analysis, we know that Sporadic ES is formed after the main storm of the Solar storm, in what we call the healing stage,” Liu added.
First, the team found sporadic es in higher latitudes, around the poles. The oddity gradually granted the equator over time. “This propagation character from top to low latitudes suggests that sporadic e layers are likely to be caused by disturbing neutral air in the e region,” Liu said.
Researchers want to understand these events because it can destroy HF (high frequency) and VHF (very high frequency) bands of areas such as navigation.
With more sense of activity in e layer in a Geomagnetic StormResearchers hope to seek ways to work in disruptions.
