Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.

Geomatics, Natural Hazards & Risk, 2019 Droughts are among the most damaging environmental disasters that may have destructive damages on societal properties and lives. Generally, socio-economic drought occurs when water resources systems could not fulfil the water demand.

The ENSO Impact on Predicting World Cocoa Prices [PDF]
Cocoa beans are produced in equatorial and sub-equatorial regions of West Africa, Southeast Asia and South America. These are also the regions most affected by El Nino Southern Oscillation (ENSO) -- a climatic anomaly affecting temperature and ...

Assessing the impact of model biases on subseasonal forecast skill
Quarterly Journal of the Royal Meteorological Society, EarlyView.Relaxation experiments where the nudging was performed towards bias‐corrected integrations of the same model display significantly improved skill at weeks 3 and 4, particularly in the northern extratropics. This indicates that there is a large potential for improving dynamical subseasonal forecasting skill by improved treatment of model biases.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We quantified the causal effect (CE) of linkages between four monthly climate indices ENSO, SMHP, RWC, and MHC for 1940–2022 with a time lag of one month. The results show CE values from (1) ENSO to SMHP of −0.33$$ -0.33 $$ to −0.44$$ -0.44 $$ (i.e., a one standard deviation (SD) increase in ENSO causes a decrease in SMHP of −0.33$$ -0.33 $$ to −0.44$$

Impact of Satellite Sea Surface Salinity Observations on ENSO Predictions from the NASA/GMAO Seasonal Forecast System [PDF]
We assess the impact of satellite sea surface salinity (SSS) observations on dynamical ENSO forecasts. Assimilation of SSS improves the mixed layer depth (MLD) and modulates the Kelvin waves associated with ENSO.

Journal of the Atmospheric Sciences, 2003 The realistic simulation of El Nino-Southern Oscillation (ENSO) by the University of California, Los Angeles (UCLA), coupled atmosphere-ocean general circulation model (CGCM) is used to test two simple theoretical models of the phenomenon: the recharge oscillator model of Jin and the delayed oscillator model of Schopf, Suarez, Battisti, and Hirst (SSBH)

Quarterly Journal of the Royal Meteorological Society, EarlyView.The change in the frequency of wet spells in tropical Australia in summer primarily contributes to the change in precipitation between wet and dry years. In the extratropics, both the frequency and intensity of wet spells are important, especially in winter.
