Time-series analysis of water environmental changes and memory characteristics in the semi‑enclosed Maowei Sea, China

This study utilizes high-frequency monitoring data and R/S fractal analysis to demonstrate that the Maowei Sea, a semi-enclosed bay in China, functions as a high-disturbance, low-inertia system with anti-persistent memory characteristics for key water quality indicators, challenging the assumption of long-term trend stability in monsoon-influenced estuarine environments.

The emergence of regional record-breaking summer heat predictability

This study demonstrates that a machine learning method utilizing global mean temperature and sea surface temperature variability can outperform dynamical models in predicting record-breaking summer heat events 5 to 10 years in advance, revealing that such predictability has already emerged in high-warming and teleconnection-influenced regions and is projected to become skillfully achievable across most land areas within the next 10 to 30 years under current warming trends.
