Improved Simulation of Gross Primary Productivity

Paul A. Dirmeyer, Editor, Journal of Advances in Modeling Earth Systems

Editor’s Highlight— A new model better explains seasonal variations in biomass. Diffuse solar radiation can increase light use efficiency in plant canopies compared to direct sunlight. This can impact terrestrial gross primary production (GPP). Yan et al. [2017] have developed a novel diffuse-fraction-based.... more

Incorporating microbial processes into earth system models

Editor’s Highlight—   Soils are the largest land-based pool of carbon. The decomposition of soil organic carbon to carbon dioxide by microbes plays a significant role as a biotic feedback to climate change. Despite decades of research, high uncertainty remains in the land-based climate change feedbacks.... more

Open-Source Tool Aims to Boost Confidence in Ice Sheet Models

Sarah Stanley, Freelance Writer

From Research Spotlights— The software could help strengthen ice sheet models to provide a better basis for policy decisions.  Massive ice sheets with layers built up over millions of years blanket most of Greenland and Antarctica. Due to climate change, these ice sheets have begun to melt.... more

Spatial scales of tropical rainfall in a changing climate

Editor’s Highlight—   This paper offers insights on spatial scales of rainfall and their mechanisms in a changing climate. The authors present results for changes in extreme precipitation in a superparameterized General Circulation Model (GCM) and how the changes differ between the GCM gridboxes and.... more

How to Find an Iceberg’s Breaking Point

Sarah Witman, Freelance Writer

From Research Spotlights— Researchers develop a mathematical method of modeling tabular icebergs, like the one that broke away from an Antarctic ice shelf earlier this year. Last month, an iceberg the size of Delaware calved, or broke away, from Larsen C, the fourth-largest ice shelf surrounding.... more

Innovation eases cloud problem in global climate and weather forecast models

Blog—  Anyone with a cell phone camera and kids or dogs knows that resolution is “expensive”: taking lots of very high-resolution photographs and video clips can quickly fill a device. An analogous resolution challenge in weather and climate modeling has dogged modelers for years: Computationally,.... more

Using magnetic field data to infer aspects of ocean circulation

Editor’s Highlight—   Conductive ocean water, when it moves through Earth’s ambient magnetic field, generates secondary electric field and magnetic fields. The poloidal part of the induced magnetic field can be observed outside the ocean at remote observatories and at satellites. It then follows that.... more

How Shifting Winds Turn Tropical Storms Into Hurricanes

Emily Underwood, Freelance Writer

From Research Spotlights— Researchers present a novel method for analyzing how wind shear affects tropical cyclone strength and structure.  Wind is a fickle force, frequently changing speed and direction. When this variation occurs over a short distance, it is called wind shear. Such sudden.... more
