The 2020 Atlantic hurricane season will go down as one of the most active seasons on record, currently second only to the incredible 2005 season in terms of the number of named storms. The 2020 season is only the second time in recorded history (the other being 2005) that the Greek alphabet has been used because the number of named storms has exceeded the number of regular names on the list. Another interesting aspect of the 2020 season has been the number of storms that have struck the northern Gulf Coast. So it is no surprise that the latest storm, Hurricane Delta, would also find its way to

NASA's multi-satellite precipitation algorithm, known as IMERG, is a tool that can help us understand recent fluctuations in Alaska's wildfires. In the summer of 2020, wildfires burned fewer acres in Alaska than in any other year during the past 10 years. In contrast, wildfires burned a record number of acres in Alaska in the summer of 2019. The image below shows the locations of satellite-detected fires and precipitation during the last two weeks of June for both years. The above image shows IMERG rainfall totals overlaid with fire hot spot detections from the Visible Infrared Imaging

During the summer, the U.S. Great Plains routinely experiences nighttime thunderstorms unlike anywhere else in the country. These large-scale storms—sometimes spanning entire states—account for more than 40 percent of annual rainfall in some areas. They can bring much-needed rain to farms and help recharge aquifers, but extremely severe events can also destroy fields, homes, and lives. Scientists have been studying the region for decades to learn the underpinnings of this distinct, repetitive weather pattern.
