If you live in or around Billings, Montana the above graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. In Billings during a normal phase of the ENSO your heating degree days pass 900HDD. However, when El-Nino phase is present the monthly average dropped to around 650.5HDD, which is a pretty significant amount especially when...
Tyrannosaurus, meaning “tyrant lizard,” was a genus of theropod dinosaur from the Late Cretaceous Period (68 to 65 million years ago).
