Highlights from the State of The Climate 2018

Just three days ago, on August 12, 2019, the American Meteorological Society (AMS) released the newest State of the Climate providing a detailed update on global climate indicators, notable weather events, and other data collected. The State of the Climate in 2018 is the 29th issuance of this international, peer-reviewed publication that is released each summer. The report is based on contributions from scientists around the world and is compiled by NOAA’s National Centers for Environmental Information. Although we can’t possibly cover all the topics in one blog post, we wanted to share some highlights with you, and we invite you to take a look at the report as well! It is full of valuable information, and we believe that an informed community is a resilient community.

Collaborative Citizen Science

Did you know that there are millions of everyday citizens across the world that are helping advance science in a wide variety of disciplines? These citizen scientists (a term that refers to everyday citizens who are intrigued by and passionate about science, but don’t necessarily have a formal scientific background) collaborate with scientists to expand opportunities for scientific data collection and to advance research in nearly every field! Dr. Kelvin Droegemeier, Director of the White House Office of Science and Technology Policy, notes that “By encouraging everyday Americans to engage in scientific research, our citizen science authorities benefit communities and the country as a whole, as well as advance our science and technology enterprise.” Whether you are interested in public health, astronomy, biology, ornithology (the study of birds!), meteorology, or pretty much anything you can think of…there is likely a project for you!

Scorching Heat Stretching from the Plains to the East Coast

A strengthening upper level ridge across the Central and Eastern United States is resulting in sweltering heat and dangerous conditions across the eastern two thirds of the country. Widespread excessive heat warnings, watches, and heat advisories are in effect, with daytime highs in the 90s to above 100 are expected. These high temperatures, combined with dewpoints soaring into the mid to upper 70s will result in over 70 million people experiencing heat indices over 100 degrees! The heat index is a measure of how hot it feels when relative humidity is factored into the actual air temperature.

Warmest heat indices expected through Monday, July 22.

Surveying the Storm

Imagine that it’s late in the evening, the sun has set, and you’re a meteorologist or the National Weather Service (NWS) exhausted from working a 13–hour day providing forecasts and warnings for a significant severe weather event that moved through your forecast area. Although the powerful storm system has exited the region, the event is not completely over. As severe weather reports filter into the office, it becomes evident that the storms caused significant damage and you’ll be heading out to conduct a damage survey first thing in the morning. Get some rest…another long day lies ahead.

This Week’s Roundup of Interesting Weather Stories

A massive plume of dust from the Sahara Desert has made its way all the way across the Atlantic Ocean into the Caribbean and the southeast United States! Known as the Saharan Air Layer (SAL), this very dry mass of dusty air normally forms over the Sahara Desert between late spring through early fall and moves out over the North Atlantic Ocean every 3-5 days. The SAL can cover an area as large as the size of the continental United States (!), and extends between ~5,000-20,000 feet in the atmosphere.

This geocolor enhanced imagery was created by NOAA’s partners at the Cooperative Institute for Research in the Atmosphere.  Its multi-band imaging capabilities provide high-resolution visible and infrared imaging of atmospheric aerosols, such as dust and sand.

NOAA: Building A Better Future

Did you know that The National Oceanic and Atmospheric Administration (NOAA) does more than forecast the weather? NOAA is a scientific agency that observes and predicts conditions in our ocean and atmosphere. From daily weather forecasts to long-term climate monitoring and from fisheries management to marine commerce, NOAA provides communities, decision-makers, and people across the country with the information they need when they need it. NOAA also understands that the agency must do more than study the ocean and atmosphere; they need to take what they learn and educate individuals, so that citizens are empowered to support their own economies by building resilient communities and healthy ecosystems. An informed society has access to, interest in, and understanding of NOAA-related sciences and their implications for current and future events.

A Brief Recap of the May 2019 Severe Outbreak

Just two short weeks ago we posted a blog that looked into the severe weather that occurred on May 20, 2019. Little did we know that this was just the beginning! Over a 12-day period that stretched from May 17 through May 30, more than 285 tornadoes touched down across 22 states. The May storms also included hailstorms (including grapefruit-sized hail in Wellington, Texas!) and frequent heavy rainfall, sometimes at record levels, over areas that were already saturated. This led to extensive flooding and flash flooding, which frequently interfered with emergency efforts related to tornado damage.

So….What is a Satellite?

According to NOAA, a satellite is a moon, planet, or machine that orbits a planet or a star. Usually the word “satellite” refers to a machine that is launched into space and moves around Earth or another body in space, but there are also natural satellites. For example, Earth is a satellite because it orbits the sun, and the moon is a satellite because it orbits the Earth. This blog will look into a variety of man-made satellites that orbit Earth.

NASA has multiple satellites that orbit the Earth.

Odisha: A Leader in Disaster Preparedness

Tropical Cyclone Fani made landfall in India around 9:30 AM on Friday, May 3 as one of the country’s strongest tropical cyclone in twenty years. Technically Tropical Cyclone Hudhud in October 2014 was somewhat stronger, but Tropical Cyclone Fani was a vastly larger system with a lot more water being carried along with it. At Fani’s peak intensity, maximum sustained wind speeds were around 150 miles per hour with gusts to around 190 miles per hour. Wind speeds were over 124 miles per hour when Fani made landfall in Odisha – home to 46 million people. Approximately 14 districts in Odisha have been affected by Cyclone Fani, over one millions people were evacuated from the storm, and approximately 900 cyclone shelters were set up for those who were displaced.

Looking back at U.S. Climate in 2018

Although most people tend to look back and on the past year around the holidays and at the beginning of a New Year, I also like to reflect back once spring has truly sprung. The sun illuminates our days even longer, the world is full of beautiful new blooms, the birds are chirping, and it seems that everything is truly “new” again. So for this week’s blog, I thought that this would be a perfect time to look back at 2018 and really take in all that happened across the U.S. weather-wise.
