MnemoClima

El Niño, the ocean and disasters, at the place you live.

MnemoClima reads public climate data on your machine and lays it on a world map and a timeline. It forecasts nothing itself. What looks ahead is NOAA's own opinion, with its date. What MnemoClima computes is the past.

The cartridge id is @mnemosyne-plugins/mnemo-clima. Its code lives at Mnemosyne-OS/MnemoClima, under the MIT licence.

The panel's tabs

• Pacific: NOAA's opinion on El Niño and La Niña, with its issue date and a link to noaa.gov. Below it, the Ocean index (ONI) and the Past episodes since 1950.
• Temperatures: the continents' averages.
• My places: your own points on the map.
• Markers: places that react early or pay later.
• Disasters: alerts in progress and their history.
• Memory: pour data into memory, watch El Niño, pin it, share it.

The map and the timeline

The map shows Ocean heat, Continents, Disasters, Tracks, Markers and Places. Draw it as a Globe or a Flat map.

The timeline holds the curves: El Niño (ONI), World (GISTEMP), N. Pacific (PDO), Indian O. (IOD), and the rain at your places. Use Zoom in, Zoom out, Since 1950 and Now. Moving the timeline moves the map to that month.

Download 1950 → today keeps the ocean heat maps on your machine, about 120 MB, once.

My places

1. Press Put a point on the map, then click where it is.
2. Give it a Name and press Keep.

MnemoClima reads 45 years of measurements at that point: rain and temperature, month by month, since 1981. The last strong El Niño, here shows what happened there after each past episode, against the normal of each month. Choose Strong (≥ 1.5) or Very strong (≥ 2.0). The table shows how many episodes it rests on, as N.

Markers

Two markers come built in: Southern California, an early sign, and Guatemala, Dry Corridor, which pays months later. A group of Coffee regions follows six producing areas. Each marker shows the last three months of rain and, where FEWS NET covers the country, its food-security phase. Add a marker adds your own.

Disasters

In progress and recent lists cyclones, floods, droughts, earthquakes, volcanoes, fires and more, with their alert level. History loads on demand: Cyclone tracks, last 3 years (about 11 MB), Earthquakes M6.5+ since 1980, Droughts and floods since 2018.

Memory and the board

• Pour into memory writes El Niño since 1950, My places since 1981, NOAA's latest opinion or The markers shown, since 1981 into a Memory Pack. The chat uses it once you choose that pack in its scope. It needs the knowledge folder, set in the Memory Packs tab of MnemoHub.
• Watch El Niño even when closed sends a notification when NOAA publishes a new opinion.
• Pin El Niño on the board puts a card on your board.
• Share the numbers writes one file per month in a folder you choose, for other apps.

Exploded view opens the map, the timeline and the panel as separate windows.

Where your data goes

Your machine reads the data from the sources. Only Natural Earth's country shapes ship with the cartridge. Your places and markers are kept by the cartridge. Ocean heat maps you download stay on this machine.

Sources named in the cartridge: NOAA Climate Prediction Center, NOAA Physical Sciences Laboratory, NASA GISTEMP, NOAA OISST, NASA POWER, GDACS (European Commission JRC), NASA EONET, USGS, NOAA IBTrACS, FEWS NET and Natural Earth (public domain).
