The correlations between monthly mean and daily mean fields which are one week before or after that month have been analysed with 15-year record of the 1000 hPa temperature for the Northern Hemisphere.It is found that the newer the daily data are,the str
Here, we want to focus on the performance of the developed ML model when used in out-of-sample (unseen) data, i.e., predictions on a dataset that is not part of both the training and testing samples. As presented in Fig. 3 and Fig. S5, the accuracy of the developed model is ...
We repeat this process until the predictions for all years are performed. Doing so allows us to use leave-one-out cross-validation to inter-annual, inter-decadal and whole time series of summer hot temperature extremes over the SRASR. For inter-annual components of detrended 1979–2016 time ...
19, 2023. (AP Photo/Daniel Cole) The world’s oceans— more than 70% of the Earth’s surface — were the hottest ever recorded, nearly 21 C (69.8 F), and have set high temperature marks for three consecutive months, the WMO and Copernicus said. “The dog days of summer are not ...
To illustrate the models' predictions, Fig. 3 shows local daily variability in mean temperature for five European cities during a warm day (2017-06-19). Due to its higher spatial resolution, the Ta and LST models developed are better at capturing within city and urban-rural Ta contrasts comp...
The predictions of the 24-h cumulative precipitation on land are quantitatively evaluated for all cases using the classic threat score (TS) while TCs are approaching or in the process of landfall (seeFig. 2andTable 1for the period of verification). The TS measures the fraction of observed eve...

2). Africa, South and Central Asia, and South America have a particularly strong signal, locally above 50% increase in the number of exceedances of the 98th percentile, i.e., twice as many hot days as in unconstrained predictions. This means models that represent ΔTX more accurately ...
