GCC (General Circulation Model)

A General Circulation Model (GCM) is a sophisticated computer program that simulates Earth's climate system, including the atmosphere, oceans, land surface, and ice. By using mathematical equations to represent physical processes, GCMs forecast how climate variables like temperature, rainfall, and wind patterns change over time. They help scientists understand current climate behavior and predict future climate scenarios under different conditions, such as increased greenhouse gases. Essentially, GCMs serve as virtual Earth systems, providing valuable insights into climate dynamics and supporting informed decision-making on climate-related issues.
