Why are Northern Hemisphere summers cooler than Southern Hemisphere summers?

The Earth is tilted on an axis of approximately 23.5 degrees relative to its orbit around the Sun. This tilt is responsible for the seasons we experience on Earth. During the summer months in the northern hemisphere, many people may notice that the temperatures in the north are cooler than those in the south, even

Dredging Impacts on Estuary Channel Tides and Water Flow: An Earthscience Study

Estuaries are important ecosystems that are highly productive due to the mixing of freshwater from rivers and saltwater from the ocean. They are also important for navigation and fisheries. Over time, however, estuaries can become shallow due to sedimentation, which can affect water flow and navigation. To maintain navigation channels and improve water flow, estuaries

Locating Archived NAM/HRRR Model Runs: A Guide for Earth Science Enthusiasts and GFS Users

As a geoscientist or user of the Global Forecast System (GFS), you may be interested in accessing archived NAM/HRRR model runs. These runs are produced by the North American Mesoscale Forecast System (NAM) and the High-Resolution Rapid Refresh (HRRR) model, both of which are used by the National Oceanic and Atmospheric Administration (NOAA) to provide

Archived Radar Data in Gridded Format: A Comparison between Environment Canada and the US

Radar is an important tool in meteorology and is used to detect and track a variety of weather phenomena such as precipitation, winds, and storms. In Canada, Environment Canada operates a network of weather radars that cover the entire country and provide valuable information to meteorologists and the general public. However, when it comes to

India’s Collision: Impacts on Mountain Building Across Asia

The collision of the Indian subcontinent with the Eurasian plate is one of the most significant tectonic events in the history of the Earth. This event began about 50 million years ago and continues to this day, giving rise to the Himalayan mountain range and the Tibetan Plateau. The Himalayas and Tibet are known for

Radioactive Dating of Meteorites Reveals Surprising Variability in Earth’s 4.5 Billion-Year Age

The age of the Earth has been a subject of scientific inquiry for centuries, and while estimates have varied over time, the current consensus is that our planet is about 4.5 billion years old. This estimate is based on a variety of methods, including radiometric dating of rocks on the Earth’s surface. However, a recent
