Observed Linkages Between Marine Heatwaves and Extreme Weather Over Land: A New Zealand Case Study

International Journal of Climatology, EarlyView.
Marine heatwaves consistently warm New Zealand's land surface, but rainfall impacts occur only when synoptic systems enable moisture transport. This 38‐year analysis shows MHWs act as thermodynamic background drivers of heat and conditional amplifiers of extreme rainfall events or droughts.

Subseasonal Predictability of Weekly Rainfall and Rainy Season Onset Over East Africa

International Journal of Climatology, EarlyView.
This study evaluates the subseasonal predictability of weekly rainfall and rainy season onset over East Africa using the ECMWF extended range forecast model. Results show strong skill in forecasting weekly rainfall up to 4 weeks ahead, with higher accuracy during the March–May ‘long rains’ season.

Research on Powder Separation by a Cyclone

Transactions of the Japan Society of Mechanical Engineers, 1952
In order to find the best condition for separating powder in desirable grain size by a cyclone, we tried to investigate the air current in the cyclone and to find out mechanism of separation. We used a Pitot tube to measure the direction, the pressure and the velocity of air flow in the cyclone.

Tracking Summer Greenland Blocking: The Upstream Pathway Shapes Historical Extremes and Future Change

International Journal of Climatology, EarlyView.
This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Toward Sustainable Enzyme Production From Agro‐Industrial Residues: Optimizing pH and Soyhull Particle Size in Fungal Fermentation

Journal of Surfactants and Detergents, EarlyView.
Sustainable enzyme production from soyhull fermentation. ABSTRACT Carbohydrase enzymes are critical to sustainable detergent formulations, enabling effective cleaning at lower temperatures and reduced resource use. To improve the economic and environmental viability of enzyme production, this study explored soybean hulls—a low‐value agricultural by ...
