Purifier: Defending Data Inference Attacks via Transforming Confidence Scores
Ziqi Yang, Lijin Wang, Da Yang +5
Neural networks are susceptible to data inference attacks such as the membership inference attack, the adversarial model inversion attack and the attribute inference attack, where…
A Vertically Resolved MSE Framework Highlights the Role of the Boundary Layer in Convective Self-Aggregation
Lin Yao, Da Yang, Zhe-Min Tan
Convective self-aggregation refers to a phenomenon in which random convection can self-organize into large-scale clusters over an ocean surface with uniform temperature in cloud-re…
Understanding the Evolution of Global Atmospheric Rivers with Vapor Kinetic Energy Framework
Aidi Zhang, Da Yang, Hing Ong +1
Atmospheric rivers (ARs) often cause damaging winds, rainfall, and floods. However, the physical mechanisms governing their evolution remain poorly understood. To close this gap, w…
The synchronization of convective lifecycles in an idealized microscopic model
Hao Fu, Da Yang
How a cloud ensemble responds to external forcing is a puzzle in tropical convection research. Convectively coupled gravity waves (CCGWs) in a finite domain have controllable wavel…
Testing the Reliability of Interpretable Neural Networks in Geoscience Using the Madden-Julian Oscillation
Benjamin A. Toms, Karthik Kashinath, Prabhat +1
We test the reliability of two neural network interpretation techniques, backward optimization and layerwise relevance propagation, within geoscientific applications by applying th…
Water vapor buoyancy and the African easterly jet
Heng Quan, Da Yang, William Boos +4
The African easterly jet (AEJ) is a prominent circulation feature in the tropical atmosphere. It transports mineral dust and generates easterly waves that serve as seeds for hurric…
Climate Bistability at the Inner Edge of the Habitable Zone due to Runaway Greenhouse and Cloud Feedbacks
Bowen Fan, Da Yang, Dorian S. Abbot
Understanding the climate dynamics at the inner edge of the habitable zone (HZ) is crucial for predicting the habitability of rocky exoplanets. Previous studies using Global Climat…
Predator and Prey: A Minimum Recipe for the Transition from Steady to Oscillating Precipitation in Hothouse Climates
Da Yang, Dorian S. Abbot, Seth Seidel
In the present tropical atmosphere, precipitation typically exhibits noisy, small-amplitude fluctuations about an average. However, recent cloud-resolving simulations show that in…
Triggered convection, gravity waves, and the MJO: A shallow water model
Da Yang, Andrew P. Ingersoll
The MaddenJulian oscillation (MJO) is the dominant mode of intraseasonal variability in the tropics. Despite its primary importance, a generally accepted theory that accounts for f…
The Rise and Fall of ENSO in a Warming World: Insights from a Lag-Linear Model
PJ Tuckman, Da Yang
The El Niño-Southern Oscillation (ENSO) is a fluctuation in sea surface temperature and pressure across the equatorial Pacific Ocean with a period of 2-7 years. As the largest mod…
One Stone, Two Birds: Using Vapor Kinetic Energy to Detect and Understand Atmospheric Rivers
Hing Ong, Da Yang
Poleward water vapor transport in the midlatitudes mainly occurs in meandering filaments of intense water vapor transport, spanning thousands of kilometers long and hundreds of kil…
Deep learning the sources of MJO predictability: a spectral view of learned features
Lin Yao, Da Yang, James P. C. Duncan +4
The Madden-Julian oscillation (MJO) is a planetary-scale, intraseasonal tropical rainfall phenomenon crucial for global weather and climate; however, its dynamics and predictabilit…
Vapor-Buoyancy Feedback in an Idealized GCM
Seth Seidel, Da Yang
Humid air is lighter than dry air at the same temperature and pressure because the molecular weight of water vapor is less than that of dry air. This effect is known as vapor buoya…
Spontaneous Cyclogenesis without Radiative and Surface-Flux Feedbacks
Argel Ramirez Reyes, Da Yang
Tropical cyclones (TCs) are among the most intense and feared storms in the world. What physical processes lead to cyclogenesis remains the most mysterious aspect of TC physics. He…
Examining Fast Radiatively Driven Responses Using Machine-Learning Weather Emulators
Ankur Mahesh, William D. Collins, Travis A. O'Brien +10
The response of the climate system to increased greenhouse gases and other radiative perturbations is governed by a combination of fast and slow feedbacks. Slow feedbacks are typic…
The Moisture-Convection Feedback Can Lead to Spontaneous Tropical Cyclogenesis
Argel RamÃrez Reyes, Da Yang
In contrast to prevailing knowledge, RamÃrez Reyes and Yang (2021) showed that tropical cyclones (TCs) can form spontaneously without moisture-radiation and surface-flux feedbacks…
