The Forecast Gift

The problem

A weather forecast is only as good as the observations beneath it. The global models that predict a cyclone's landfall or a drought's onset run on data from every station, balloon, buoy and radar that reports into the shared system the world's weather services maintain, and where there are no stations, the model is guessing. Africa is where it guesses most. The continent operates about 37 weather radars for 1.2 billion people, one for every 32 million, a coverage deficit of about eighteen times against the rich world. In 2019 only 20 percent of African weather stations met the World Meteorological Organization's standards, and many of those that exist do not report into the global system at all. Tropical Africa, where a billion people will farm, build and shelter this century, is the largest hole in the world's picture of its own weather.

The consequences are counted in the famine of № 063 and in the floods that kill thousands a year without warning. A farmer in the Sahel who knew the rains were late would plant differently; a mayor in Mozambique who had 72 hours' notice of a cyclone would move people. The United Nations' Early Warnings for All initiative, launched in 2022, aims to give every person on earth warning of hazardous weather by 2027, and the financing facility built for it, which funds basic observing stations in the poorest countries, lists thirteen African nations in its first phase. The gap is measured in a few thousand stations and a few dozen radars: a rounding error in the budget of any rich weather service.

The United States has the asset that makes the gift possible. The National Weather Service and NOAA run the most capable forecasting system in the world and, by law and by long practice, publish most of its data free to anyone, including the rainfall estimates for Africa that the Famine Early Warning network relies on. № 063 made the warning network a statutory office. This proposal builds the stations that feed it, and gives the forecast to the people who need it in a form they can act on.

The proposal

The Forecast Gift: the United States funds, through the World Meteorological Organization's financing facility and directly, the observing network Africa lacks: 5,000 automated weather stations, 100 radars, and the upper-air and ocean observations to standard, with the data reported into the global system and published free. American forecasters are seconded to African weather services, and NOAA's models and warnings are delivered, in local languages, to phones. The Island Compact's Pacific stations come first.

How it would work

1. The stations. Five thousand automated surface stations, built to the international standard, sited by the host weather services to close the gaps the global system identifies, and maintained under ten-year service contracts so that they do not fall silent when the grant ends, which is what has happened to most stations built by donors. The cost of a station is a few tens of thousands of dollars; the cost of maintaining it is the part donors forget.

1. The radars. One hundred weather radars, sited for the populations at greatest risk of flood and storm, roughly tripling the continent's coverage. A radar sees the rain before it falls on the city.

1. The balloons and the sea. Upper-air observations, the twice-daily balloon launches that the models need most, at the sites the WMO's basic network specifies; and ocean buoys in the Gulf of Guinea and the western Indian Ocean, where the cyclones that strike Mozambique and Madagascar form.

1. The data, both ways. Every observation the Gift funds reports into the global system, free, as the American stations do; and every forecast NOAA produces for the region is delivered to the host weather services and, in local languages, to the public, through the phones that most of the continent now carries. The Tongue Commons of № 115 supplies the languages.

1. The people. American forecasters and technicians seconded to African weather services for two-year tours under the Builder Corps of № 110, each training two local counterparts. A station without a technician is a station that will be silent in three years.

1. The islands first. The Island Compact's nations of № 108 live on atolls two metres above the sea; their stations are funded in the first year.

1. The count. Stations reporting, radars operating, forecasts delivered, and, over time, deaths in weather disasters in the countries covered, published annually. The gift's measure is the warning that arrived.

The numbers

The stations. 5,000 at about $30,000 each, plus maintenance: about $150 million to build and about $50 million a year to keep reporting. The radars: 100 at $3 to $5 million each, about $400 million, and $40 million a year to run. Balloons and buoys, on the order of $50 million a year. The total is about $600 million to build and about $150 million a year to sustain: less than the cost of a single American weather satellite.

The return. The World Bank estimates that every dollar spent on hydrometeorological services in developing countries returns between three and ten dollars in avoided losses and better decisions, before counting lives. The Global Commission on Adaptation put the return on early warning systems at about ten to one.

The coverage. From 37 radars to about 140; from a fifth of stations meeting standard to most; from the world's largest observational hole to a continent that reports.

What it buys the giver. The forecast that saved the harvest carries the name of the service that issued it. Nothing a rival power builds on the continent will be consulted by as many people every morning.

The honest objections

"Donors have built weather stations in Africa for decades and most of them are dead." True, and the reason is in item 1: they were built and not maintained. The Gift's cost is mostly maintenance, on ten-year contracts, with technicians trained under item 5. A station that reports for a decade is the Gift's unit of delivery; a station that is built is not.

"Satellites make ground stations obsolete." Satellites see the cloud tops; ground stations measure the rain, the temperature and the pressure that the models assimilate, and the models are measurably worse where the ground is silent. NOAA runs both because both are needed, and Africa has neither in sufficient quantity.

"This is charity, not strategy." It is both, which is the catalog's position on the Open Hand generally. Weather data is the most shared public good in the world, by treaty and by practice, and the country that fills the continent's largest gap in it will be the country whose forecast is on every phone. China has offered African weather services its own satellite data and stations; the Gift offers more, free, into the open system.

"$150 million a year forever." For the observing network of a continent of a billion people, yes. The National Weather Service's budget is about $1.4 billion a year for a country of 340 million. The Gift is a tenth of that for three times the people.

"African weather services cannot absorb the equipment." Some cannot today, which is why the technicians are seconded and trained, why the maintenance is contracted, and why the phases begin where the services are strongest and the risk is highest. The WMO's own network-designation work shows which services can report now and which need the decade.
