Deriving shallow water equations: why is the vertical velocity equal to the material derivative of the surface level?
Modeling & PredictionLet’s dive into the shallow water equations, those fascinating tools we use to describe how water flows in relatively shallow environments. Think rivers, lakes, or even the coastline – places where the depth is significantly less than the horizontal reach. These equations are derived from some pretty heavy-duty physics, the Navier-Stokes equations, but with a
Unraveling Earth’s Ancient Supercontinents: Exploring the Distinct Paleogeographic Features of Kenorland and Arctica
Historical AspectsUnraveling Earth’s Ancient Supercontinents: Exploring the Distinct Paleogeographic Features of Kenorland and Arctica Ever wonder how the continents we know today came to be? It’s a story billions of years in the making, a tale of colossal landmasses crashing together and then splitting apart. These supercontinents, as they’re called, have shaped everything from our climate
Unraveling the Enigma: Decoding the Strange Results of the SWAN WAVE Model in Earth Science Wave Modeling
Modeling & PredictionOkay, so you’re wrestling with weird results from your SWAN model? You’re not alone. This thing, the Simulating WAves Nearshore model, is supposed to be our go-to for predicting wave action near the coast. And most of the time, it’s a lifesaver. But every now and then, it spits out something that just doesn’t make
Analyzing the Implications: SWAN’s Inability to Simulate Wave Dynamics in Earth Science
Modeling & PredictionLet’s Talk Waves: Where SWAN Soars and Where It Swims a Little… Off Okay, so you’re dealing with coastal stuff, right? Maybe you’re worried about erosion, designing a harbor, or just trying to figure out how those waves are behaving. Chances are, you’ve run into SWAN – Simulating Waves Nearshore. It’s the go-to model for
Is there a mountain-shaped iceberg?
Polar & Ice RegionsIcebergs: Nature’s Frozen Sculptures – Could One Actually Look Like a Mountain? Icebergs! Just the word conjures up images of colossal, icy behemoths drifting serenely across the ocean. They’re like frozen sculptures, remnants of glaciers and ice shelves, and they never fail to inspire awe. But have you ever wondered if one of these icy
The Dynamic Prime Meridian Shift: Exploring Google Earth’s Panoramic Perspective on Earth’s Longitude
Natural EnvironmentsThe Prime Meridian: It’s Not Where You Think It Is (and Google Earth Knows!) Okay, so you probably think you know where the Prime Meridian is, right? Greenwich, England, that famous line running through the Royal Observatory. Well, buckle up, because it’s a bit more complicated than that! For centuries, this line of 0° longitude
