Supercomputer says no: gridding the Earth in next-generation weather and climate models

Posted on February 10, 2014 by Andrew McRae

Making a timely weather forecast, or running a high-resolution global climate model, requires the use of a massive supercomputer. Simulations that would take months to run on a normal computer take just hours on a supercomputer. However, supercomputers are far … Continue reading →

Hydrology and hydrological model

Posted on January 29, 2014 by Lu Li

Quite often people ask me about my field of study in parties or activity groups out of geo department. When I answer: “hydrology”, there is a large chance that a big question mark shows on their face with a “not … Continue reading →

A History of Climate Models

Posted on January 22, 2014 by Metal Bonsai

Many PhD researchers use climate models with little thought of how they were developed. Often there just isn’t time in modern schedules to investigate their history. How these models evolved through the ages is pretty interesting and involves battling mathematicians … Continue reading →

The making of an ocean wave (forecast)

Posted on October 11, 2013 by Johannes Röhrs

A big winter storm is brewing in the North Atlantic. Meteorologists on TV exclaim that there is a developing storm system just south of Iceland, and that the current position of the polar front will most likely steer the low … Continue reading →

Small talk – the model way

Posted on May 17, 2013 by Aleksi Nummelin

This snack is hopefully the first in a series discussing the uncertainties and errors in climate simulations. I feel this important topic is often misunderstood by public and even by scientists, but it is of great importance when trying to … Continue reading →
