气候服务与预警
Climate services turn observations, forecasts and projections into information people can use: daily forecasts, seasonal outlooks, warnings and climate guidance for sectors. A warning only works if it reaches people in time, in a form they understand, and if they know what to do. This page sets out how services and warning 系统 are organised, how forecasts are verified, and what evidence serves the services and authorities that run them.
工作如何开展。
图Multi-hazard outlook: example names and illustrative values, not a record or a live system.
Climate services and warnings: how the risk develops.
Forecast-to-user pathways and authority. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Detection and forecasting
Observing networks, radar, satellites and numerical models detect developing hazards and forecast them. 提前量 and skill vary by hazard, from days for cyclones to minutes for flash floods.
Impact-based warnings
Warnings that describe what the weather will do, such as roads flooding or buildings at risk, prompt more action than warnings that only give rainfall amounts or wind speeds.
The last mile
Warnings must reach everyone through broadcast, mobile alerts, sirens and community networks, in local languages and accessible formats. Gaps fall hardest on remote, poor and marginalised people.
Trust and response
People act on warnings they trust and understand. False alarms, unclear authority and conflicting messages erode trust, while drills and preparedness turn warnings into action.

Model climate services and warnings as a system. Run the cascade.
Assembled from the Nexus Standards area profile 气候风险标准: the hazards it names, the 系统 and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

专家提出的问题。
The questions follow information from forecast to action.
- How skilful are forecasts at the lead times that matter for a given action?
- Who has the legal mandate to issue a warning, and does everyone know who that is?
- Do warnings describe likely impacts, not only weather, and say what to do?
- Do they reach everyone at risk, including people without phones, in other languages or with disabilities?
- What happens when a warning turns out to be a false alarm or a miss?
机制与驱动因素。
Forecast skill declines with lead time and varies by hazard: large-scale storms can be forecast days ahead, while intense local downpours are hard to pin down even hours before. Seasonal forecasts give probabilities, not certainties. Impact-based warnings combine hazard forecasts with exposure and vulnerability to describe what the weather will do, which people find easier to act on.
Warnings fail most often in the last mile: unclear authority, conflicting messages, messages that do not reach people, or advice that is impossible to follow. Trust is built over time, and repeated false alarms or missed events erode it. A single authoritative voice, consistent messages and clear actions are widely recognised as essential.
如何研究,以及方法止于何处。
| 方法或数据 | 显示内容 | 局限 |
|---|---|---|
| 预报检验 | Skill, reliability and bias at given lead times | Rare extremes give few cases for verification |
| Warning chain and stakeholder mapping | Who issues, relays and acts on warnings | Formal arrangements may differ from practice |
| Post-event reviews | Whether warnings were received, understood and acted on | Rely on recall and partial data |
| Social and behavioural research | Why people do or do not act | Findings are context-specific |
