Exploiting Domain Knowledge to Address Class Imbalance in Meteorological Data Mining

open access: yesApplied Sciences, 2022
We deal with the problem of class imbalance in data mining and machine learning classification algorithms. This is the case where some of the class labels are represented by a small number of examples in the training dataset compared to the rest of the ...

Why the Increasing Trend of Summer Rainfall over North China Has Halted since the Mid-1990s

open access: yesAdvances in Meteorology, 2020
Previous studies indicate that the summer (July-August) rainfall over North China has decreased since the mid-1970s due to the weakening of East Asian summer monsoon (EASM). However, this study firstly discovers the new evidences that the summer rainfall

Impacts of Different Onset Time El Niño Events on Winter Precipitation over South China

open access: yesAtmosphere, 2018
Winter precipitation over South China tended to be much higher than normal for the spring El Niño events during 1979–2016. For the spring El Niño events, the meridional and zonal circulations served as a bridge, linking the warmer sea

Adaptive neuro fuzzy inference system for predicting sub-daily Zenith Wet Delay

open access: yesGeodesy and Geodynamics, 2022
In recent years, the focus of tropospheric studies has evolved to GNSS meteorology and weather forecasting. The Zenith Wet Delay (ZWD), which might be assembled to the Integrated Water Vapour (IWV), is an essential component of the tropospheric delay ...
