Use of S2S forecasts in applications Andrew W. Robertson ECMWF Workshop on sub-seasonal predictability, Nov 2–4, 2015 Outline • Types of user and application, and entry points for obtaining S2S forecasts - developed and developing country users • Tailored forecast information and verification • Question of most user-relevant formats for forecasts on different time scales (weather-S2S-seasonal) Types of user and application • Hazard early warning - enhancing preparedness to high-impact weather events • Management decisions in weather-sensitive operations • Large range of users from sophisticated to developing country Hydrologic Forecasts of spring flood volumes for Hydropower Short range forecasts, up to 10 days ahead ▪Based on a meteorological forecast ▪Most valuable at high flows (flood warnings), and for short term reservoir planning Long range forecasts, 1 to 6 months ahead ▪Climatological forecast based on historical precipitation and temperature records ▪Most valuable for water resources planning and operation of reservoirs Kean Foster 4 ModelDecision (WEAP), (b) Climate-Agriculture Support Model (CAM), and (Toolsc) Knowledge Sharing for Portal Climateand Maproom (KSPM).

Decision Support Tools for Climate ResilientResilient Agriculture in the Agriculture in the Philippines Bicol Region Water Evaluation and Planning (WEAP) Model Vulnerability to Climate Risks WEAP is a computer-based software tool that provides users with an integrated approach for water resources The Bicol Region, located in the southeastern part of Luzon, Philippines, is vulnerable to climate-related planning and management in a river basin. As a customized tool, WEAP-Bicol uses climate and hydrological data hazards such as typhoons, floods, and dry spells. Such (e.g., rainfall amount, river water flow and irrigation needs) and calculates water supply available to users in the vulnerability translates to large agricultural losses The Bicol Agri-Water Project - a USAID grant implemented by the University of the affecting the economic livelihoods Bicol’s population, Quinali A and Buhi-Barit watersheds. The tool can also be applied at various scales including river basin, sub- 39% of whom work in the agriculture and fisheries watershed, and farm level.

With long-term climate change Schematic diagram of WEAP Model impacts posing uncertainty in the region’s agriculture sector, there is a need for ‘agro-climate tools’ to improve 3 local capacities to anticipate and respond to climate risks to support Bicol’s long-term food security.

Ines Functionally, WEAP-Bicol is linked with the CAMDT and the KSPM, acting both as a source and user oF data/information from these two other decision support tools. Its interface with the CAMDT can help users, For example, understand how simulated water availability will affect crop management options. Meanwhile, climate and hydrological data from KSPM are inputs For the models that WEAP-Bicol will generate, which in turn will be made available to users through the KSPM website. Climate-Ag Modeling Decision Tools (CAMDT) The CAMDT is a computer desktop tool designed to guide decision-makers on adopting appropriate crop and water management practices that can improve crop yields given a climatic condition. It is a suite oF tools, starting with IRI’s Climate Predictability Tool (CPT) and PAGASA’s seasonal climate forecasts that Feed climate data to an analytical tool called, Decision Support System For Agrotechnology Transfer (DSSATv4.5) crop models, to extract risk profiles of crops, specifically rice, planted at diFFerent time windows. Decision-makers can use the risk profile to analyze the specific variety to plant and farming logistics and inputs to use.
