صحت‌سنجی پهنه و هیدروگراف سیلاب با استفاده از داده‌های بارش ERA5 (مطالعه موردی: حوضه زشک) [PDF]

جغرافیا و مخاطرات محیطی, 2022
بارش یکی از اصلی‌ترین عوامل وقوع سیلاب‌هاست که به علت عدم پراکندگی مناسب ایستگاه‌های باران‌سنجی و تازه‌تأسیس‌بودن برخی از این ایستگاه‌ها در اکثر حوضه‌های کشور، استفاده از داده‌های بارش با چالشی جدی روبروست. ازاین‌رو روش‌های دورسنجی می‌توانند یکی از گزینه‌

Evaluation of ERA5 and ERA5-Land Reanalysis Precipitation Data with Rain Gauge Observations in Greece

16th International Conference on Meteorology, Climatology and Atmospheric Physics—COMECAP 2023, 2023
Precipitation is a key component of the hydrological cycle and directly affects water availability and hydrometeorological hazards. The objective of this study is to evaluate the performance of two reanalysis precipitation datasets, ERA5 and ERA5-land, in reproducing precipitation accumulations over Greece.

Influence of Sea-Ice Anomalies on Antarctic Precipitation Using Source Attribution in the Community Earth System Model [PDF]

, 2020
We conduct sensitivity experiments using a general circulation model that has an explicit water source tagging capability forced by prescribed composites of pre-industrial sea-ice concentrations (SICs) and corresponding sea surface temperatures (SSTs) to

Mean radiant temperature from global-scale numerical weather prediction models [PDF]

, 2020
In human biometeorology, the estimation of mean radiant temperature (MRT) is generally considered challenging. This work presents a general framework to compute the MRT at the global scale for a human subject placed in an outdoor environment and ...

Simulating model uncertainty of subgrid-scale processes by sampling model errors at convective scales [PDF]

, 2020
Ideally, perturbation schemes in ensemble forecasts should be based on the statistical properties of the model errors. Often, however, the statistical properties of these model errors are unknown. In practice, the perturbations are pragmatically modelled

GPM-IMERG product: a new way to assess the climate change impact on water resources in a Moroccan semi-arid basin

Journal of Water and Climate Change, 2022
Due to the lack of observed data, climate change impact studies are difficult to conduct. This paper evaluates the effect of climate change on water resources, in a Moroccan basin, using the Final Integrated Multi-satellitE Retrievals for Global ...
