Hydrological cycle over the Iberian Peninsula, precipitation forecast.

The global atmospheric reanalyses suffer from limitations associated with their coarse spatial resolution; they do not allow adequately resolving small-scale physical processes. In this sense, the main objective of the project is to investigate the ability to produce high-resolution atmospheric fields using mesoscale integrations to resolve the details of small-scale processes.

To achieve that objective, measurements from traditional sensors such as soundings, remote sensors (UHF and VHF profilers, GPS or satellites) and estimations by means of numerical models (WRF and WRFDA) have been used with the aim of closing the atmospheric hydrological cycle over the Iberian Peninsula.

The outcome of the project is an improved high-resolution quantitative estimate of atmospheric moisture balance over the Iberian Peninsula.

全球大气再分析在空间分辨率方面存在局限性，无法充分解析小尺度物理过程。在此意义上，本项目的核心目标是探究利用中尺度积分来解析小尺度过程细节，从而产生高分辨率大气场的能力。为实现此目标，项目组已采用传统传感器（如探空、遥感传感器（UHF和VHF测风雷达、GPS或卫星））的测量数据以及数值模型（WRF和WRFDA）的估算结果，旨在闭合伊比利亚半岛的大气水文循环。项目成果为伊比利亚半岛大气水分平衡的高分辨率定量估计提供了改进。本研究得到（CGL2013-45198-C2-1-R和CGL2016-76561-R，MINECO/ERDF，UE）项目的资助。S.J.G.R.受益于MINECO提供的FPI博士后研究奖学金（BES-2014-069977）。此外，来自埃希哈大学（UPV/EHU，GIU 14/03）的额外资金支持了本项目。项目中所使用的密集计算资源由I2BASQUE提供。
