特别观测期（SOP1）是 HyMeX 活动（地中海实验中的水文循环，2012 年 9 月 5 日至 11 月 6 日）的一部分，专门监测地中海西部的强降水事件和山洪暴发，并确定了三个意大利水文气象监测点：利古里亚-托斯卡纳、意大利东北部和意大利中部。包括仪表飞机在内的先进仪器的非凡部署，以及包括水文模型和海洋模型在内的多种不同业务天气预报模型的使用，使得对意大利水文气象站点周围的高影响天气事件进行了前所未有的监测和分析。这项活动见证了意大利科学界和运营界之间的密切合作。本文概述了 SOP1 期间意大利组织的情况，并描述了选定的强化观察期 (IOP)。为该分析选择每个意大利目标区域的重要事件：意大利东北部的IOP2（2012年9月12日至13日）、意大利中部的IOP13（2012年10月15日至16日）以及利古里亚和托斯卡纳的IOP19（2012年11月3日至5日）。对于每个IOP，都会对气象特征以及特殊观测和天气预报进行分析，目的是突出预报建模系统的优点和缺点，包括水文影响。最终针对其中一个事件（IOP19）显示了以不同数值天气预报模型和/或不同模型设置或初始条件为特征的不同天气预报操作链的有用性。
The Special Observation Period (SOP1), part of the HyMeX campaign (Hydrological cycle in the Mediterranean Experiments, 5 September–6 November 2012), was dedicated to heavy precipitation events and flash floods in the western Mediterranean, and three Italian hydro-meteorological monitoring sites were identified: Liguria–Tuscany, northeastern Italy and central Italy. The extraordinary deployment of advanced instrumentation, including instrumented aircrafts, and the use of several different operational weather forecast models, including hydrological models and marine models, allowed an unprecedented monitoring and analysis of high-impact weather events around the Italian hydro-meteorological sites. This activity has seen strong collaboration between the Italian scientific and operational communities. In this paper an overview of the Italian organization during SOP1 is provided, and selected Intensive Observation Periods (IOPs) are described. A significant event for each Italian target area is chosen for this analysis: IOP2 (12–13 September 2012) in northeastern Italy, IOP13 (15–16 October 2012) in central Italy and IOP19 (3–5 November 2012) in Liguria and Tuscany. For each IOP the meteorological characteristics, together with special observations and weather forecasts, are analyzed with the aim of highlighting strengths and weaknesses of the forecast modeling systems, including the hydrological impacts. The usefulness of having different weather forecast operational chains characterized by different numerical weather prediction models and/or different model set up or initial conditions is finally shown for one of the events (IOP19).
