A First Evaluation of ERA5-Land Reanalysis Temperature Product Over the Chinese Qilian Mountains

Frontiers in Earth Science, 2022
Reanalysis temperature products are important datasets for temperature estimates over high-elevation areas with few meteorological stations. In this study, surface 2 m air temperature data from 17 meteorological stations from 1979 to 2017 in the Qilian ...

Developing a global operational seasonal hydro-meteorological forecasting system: GloFAS-Seasonal v1.0 [PDF]

, 2018
Global overviews of upcoming flood and drought events are key for many applications, including disaster risk reduction initiatives. Seasonal forecasts are designed to provide early indications of such events weeks, or even months, in advance, but ...

Spatiotemporal Changes in Precipitation Concentration in the Atlantic‐European Region

International Journal of Climatology, EarlyView.
This study analyses changes in precipitation concentration using ERA5 and E‐OBS datasets. Gini index as a measure of precipitation concentration revealed a gradual expansion of areas with increasing unevenness in precipitation distribution across the Atlantic‐European region since 1961.

Sampling Biases in Daily Average Temperatures From Greenland Climate Records

International Journal of Climatology, EarlyView.
Biases are introduced in the calculation of daily average temperatures due to uneven sampling times for the investigated weather station network in Greenland. The figure shows the network, an example of a daily temperature cycle with daily averages based on all or only two observations and an overview of how the number of observations per day changes ...

Large Proportions of Surface Ozone and Premature Mortality Due to a Stratospheric Intrusion Event in North China

International Journal of Climatology, EarlyView.
This study, by examining a typical stratospheric intrusion event that occurred in North China from 30 to 31 July 2021, found that the event led to a sharp increase in near‐surface ozone concentrations by 23 ppbv within 36 h, accounting for 40% of the total observed ozone levels, with localised peaks exceeding 30 ppbv.

Spatiotemporal Droughts Propagation and Direct Driving Variables Under Climate Change Projections: A Case Study of Tunisia

International Journal of Climatology, EarlyView.
Drought spatiotemporal propagation and direct driving variables are assessed at multiple time steps with high spatial resolution using various drought indices (SPI, SPEI and SPDI) and entropy based mutual information under an ensemble of climate change projections over Tunisia. ABSTRACT Projecting drought occurrence and spatiotemporal propagation under

Projected Intensification of Hydroclimatic Extremes in Rio Grande do Norte, Brazil, Under CMIP6 Scenarios

International Journal of Climatology, EarlyView.
The graphical abstract presents observed (1963–2023) and projected changes in hydroclimatic extremes in Rio Grande do Norte, Brazil. It integrates dry‐spell duration (CDD) and extreme precipitation (R95pTOT) using CMIP6 multimodel ensembles under SSP1‐2.6, SSP2‐4.5, and SSP5‐8.5.

How Well Is Surface Diurnal Temperature Range Represented by Observations at 2‐m Level

International Journal of Climatology, EarlyView.
We demonstrate that geostationary satellites depict well the Diurnal Temperature Range (DTR) in the US but differ from information at 2 m level from model outputs. Upper: mean diurnal temperature range (DTR) using GOES‐E based land surface temperature (LST) for January (left) and July (right) during 2004–2009. Lower: mean diurnal temperature range (DTR)

Evaluating the performance of key ERA‐Interim, ERA5 and ERA5‐Land climate variables across Siberia

International Journal of Climatology
AbstractReanalysis datasets provide a continuous picture of the past climate for every point on Earth. They are especially useful in areas with few direct observations, such as Siberia. However, to ensure these datasets are sufficiently accurate they need to be validated against readings from meteorological stations.
