2021: Nearly as Many Billion Dollar Disasters as Record 2020 Season – Drought Spells Trouble for Hydropower – Can Grid Handle Renewable Revolution?

Maps Still Don’t Look Like Late October. NOAA’s GFS model roughly 2 weeks out shows a massive ridge of high pressure over the western US and much of western Canada, which suggests another warming trend by the third of fourth week of October. At this rate I wouldn’t be shocked to see a few more 70s within 2 weeks or so. World Meteorological Organization Sharpens Warnings About Both Too Much and Too Little Water. Inside Climate News reports: “The global supply of fresh water is dropping by almost half an inch annually, the World Meteorological Organization warned in a report...

Fall Color Factors, As Explained by Paul Douglas!

The leaves are leaving, but not before a brilliant, Technicolor explosion of color! Why do leaves even change color? As the days get shorter in the fall, there is less sunlight for photosynthesis. Plants convert carbon dioxide in the air into sugars (glucose and starch) and oxygen by using energy from the sun through the process of photosynthesis. Chlorophyll is the green pigment necessary for photosynthesis. A decrease in photosynthesis that comes with less daylight means trees stop producing chlorophyll. As the green pigment fades over time other pigments present in the leaf are revealed, producing a veritable explosion of...

Water Stress Increases Need for Reliable Weather Data to Power US Agriculture

“If there is magic on this planet, it is contained in water”, wrote Loren Eiseley. As a meteorologist, that quote has stuck with me over the years. But a warmer, more volatile climate is putting Earth’s hydrological cycle on fast-forward. The wets are trending wetter, the dries are drier. We are faced with too much water – or not nearly enough. The western US is enduring a 1200-year “Megadrought”, made worse by climate change. Cities are running out of water; fires and thick palls of smoke have become a daily fixture on local weather maps; all while a 7-8% increase...

Hurricane Henri Approaching the Northeast
August 26

Querying for Historical Tropical Cyclone Data with the AerisWeather API

As Hurricane Henri approached the Northeastern US this past weekend, I wondered how often a tropical cyclone has come within 50 miles of New York City, Boston, or other cities. How many were hurricanes? To answer these questions, we can use the Tropical Cyclones Archive endpoint within the AerisWeather API. This endpoint provides access to the complete AerisWeather historical archive for tropical systems, with data from the late 1800s for the Atlantic basin and the mid-1900s for the Pacific basin. When using the tropical cyclones archive endpoint, we find that 21 tropical cyclones have tracked within 50 miles of New York...

Visualizing Severe Storm Threats

Tracking Storm Threats With the Severe Weather Module

In March, we introduced the popular Severe Weather Module for use with the AerisWeather Interactive Map App to track storm threats. We’ve since added a new feature that allows you to tap into the power of the AerisWeather Threats endpoint within the Interactive Map App. There’s no need to write code to query the AerisWeather API Threats Endpoint, we’ve taken care of the hard part. All you have to do now is click on the map to display approaching storm threats in the infopanel. Threats Endpoint Background The Threats Endpoint is one of many severe weather endpoints in the AerisWeather API. It’s much more than just National Weather Service warnings, it utilizes a plethora of other meteorological-related parameters as well...

Announcing Minutely Precipitation Forecasts

How soon will it rain? How intense will it be? As of today, these questions can now be answered with the release of our new Minutely Precipitation support! Last year, we introduced the conditions endpoint that provides current weather conditions for any global location. Since, we’ve continued to enhance this endpoint and expanded our global historical access through 2011. Now we are excited to announce the conditions endpoint can now support Minutely Precipitation forecasts. What is a Minutely Precipitation Forecast? Minutely Precipitation provides the forecast precipitation rate in 1-minute intervals for the next 60 minutes. AerisWeather generates these high-resolution forecasts...

6 AerisWeather Features to Convert Mobile App Users to Paid Subscribers

In 2020 alone, mobile apps from the App Store and Google Play Store grossed more than $111 billion from in-app purchases according to SensorTower – a nearly three-fold increase from 2016. With so many great mobile apps launching every day in a hyper-competitive market, developers need to understand what options they have in providing value to app users to remain relevant in the marketplace. We’ve all thumbed through poorly-designed apps and been interrupted by ads that completely disrupt the user experience, it’s unpleasant and distracting when done incorrectly. As an alternate means of monetization, weather-influenced apps are rapidly shifting their model to...
