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...

Hurricane Henri Approaching the Northeast

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...
