AGU期刊一周Research Spotlight (Jan 25~Feb 1, 2019)

Climate Change

1.    Finding Sources of Uncertainty in the Spatial Pattern of Warming

The planet is heating up, but uncertainty still exists about how temperatures will change in specific regions. A new study examines sources of uncertainty in the meridional pattern of warming.

2.    Atlantic Overturning Circulation Questions Abound

Over the past 2 decades, the Atlantic Meridional Overturning Circulation (AMOC) has undertaken an international enterprise to observe and predict the Atlantic component of the global overturning circulation system.

3.    Advancing Climate Science and Response for Caribbean Islands

Researchers have called for greater resilience within individual states and collectively across the Caribbean, especially given the projections that extreme weather variability will continue.

4.    Indigenous Symposium on Water Research, Education, and Engagement

Indigenous communities in the United States and globally face pressing water challenges, including threats from resource extraction methods and climate change. Hydrology as a discipline will benefit from deeper integration with indigenous knowledge systems.

Hazards & Disasters

1.    A Space Weather Threat in the Mediterranean Region?

The impact of space weather on power grids in Mediterranean countries, such as Italy, needs deeper assessment, including consideration of coastal effects, ground conductivity, and failure reports.

2.    The Unpredictability of Floods, Erosion, and Channel Migration

A new algorithm incorporates randomness into stream channel formation and suggests the approach represents regions with variable flood magnitudes better than standard models.

3.    Earth’s Devastating Power, Seen by Satellite

Hurricanes, volcanoes, droughts, floods, fires, tsunamis: Satellites capture some of Earth’s most destructive forces.

Space & Planets

1.    Apollo May Have Found an Earth Meteorite on the Moon

The meteorite may have been blasted off of Earth during an impact, mixed with lunar rocks, and brought back to Earth 4 billion years later by astronauts.

2.    New Plasma Wave Observations from Earth’s Magnetosphere

The first simultaneous observations of multiple electromagnetic wave types in Earth’s magnetosphere may inaugurate a new field of inquiry into cross-frequency wave interactions.

3.    Researchers Bring Early Martian Water Chemistry to Life

Lab experiments constrain conditions necessary for a key mineral to have formed in ancient lagoons and a crater lake.

Atmospheric Sciences

1.    Stroke Deaths Rise, Life Expectancy Falls with Polluted Air

The connection between poor air quality and higher stroke mortality was strongest in southern states across a region known as the “stroke belt.”

2.    Training a New Generation of Data-Savvy Atmospheric Researchers

Pacific Northwest National Laboratory and the University of Washington team up to teach students about state-of-the-art research instrumentation.

Geohealth

1.    Peering into Pores: What Happens When Water Meets Soil?

New research sheds light on the long-standing puzzle of how and why soil water density differs from free water density.

Ocean Sciences

1.    Waves of Deadly Brine Can Slosh After Submarine Landslides

Brine pools—hypersaline, low-oxygen waters deadly to many forms of ocean life—can experience waves hundreds of meters high when hit by a landslide, potentially overspilling their deep-sea basins.
