Could the chemical industry mitigate rapid global cooling from a catastrophic volcanic eruption?

open access: yesAIChE Journal, EarlyView.
Abstract Estimates based on historical data place the probability of a catastrophic volcanic eruption in the next 100 years at around one in six. Large volcanic eruptions can lead to significant global cooling for 2–4 years, with potentially devastating impacts on global agriculture.

Predictability of European winter 2020/2021: Influence of a mid‐winter sudden stratospheric warming

open access: yesAtmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022
Boreal winter 2020/2021 was characterised by a negative North Atlantic Oscillation (NAO) pressure pattern, yet the signals from the ensemble mean of many seasonal forecast systems were for a positive NAO. In this letter we focus on the GloSea5 seasonal forecast system and investigate if there is any evidence for forecast error, or whether the ...

Multifunctional Position and Stiffness Control of Soft Fluidic Actuators Using Supercooled Liquid

open access: yesAdvanced Intelligent Systems, EarlyView.
This work explores the use of supercooled liquid as a multifunctional working fluid for soft actuators to allow independent control of position and stiffness; the solution is used to both inflate the elastomer chambers while in liquid state and to achieve a dramatic increase in stiffness (up to 13 times) with rapid, reversible crystallization.

Distinct response of near surface air temperature to clouds in North China

open access: yesAtmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022
Cloud weakens Tmax and increases Tmin, and thus decreases daily temperature range (DTR), which is mainly due to the blocking effects of clouds to downwelling solar radiation and trapping effects to upwelling longwave radiation. However, the relative impacts of clouds on Tmax and Tmin vary with locations, with relatively stronger impact on Tmin and DTR ...

Multi‐Distance Spatial‐Temporal Graph Neural Network for Anomaly Detection in Blockchain Transactions

open access: yesAdvanced Intelligent Systems, EarlyView.
This paper presents a novel Multi‐Distance Spatial‐Temporal Graph Neural Network for detecting anomalies in blockchain transactions. The model combines multi‐distance graph convolutions with adaptive temporal modeling to capture complex patterns in anonymized cryptocurrency networks.

Upper‐level midlatitude troughs in boreal winter have an amplified low‐latitude linkage over Africa

open access: yesAtmospheric Science Letters, Volume 24, Issue 1, January 2023., 2023
Composite mean anomaly of 850‐hPa temperature at 10–15° N 2 days after the strongest midlatitude upper‐level trough days. The troughs are located at the longitude shown on the x‐axis, and the temperature is measured 16.5° longitude downstream (east) of the trough. Black dots indicate statistical significance.
