Extreme sea-level analysis
Tide gauge records are separated into tide, surge and mean sea level, and extremes are combined with sea-level projections to estimate future lehiya peravê levels.

Ocean and coastal science supplies the marine drivers of climate hazards: bilindbûna asta deryayê, bilindbûna ava behrê ya bahozê, waves, marine heatwaves and the ocean’s role in cyclones and climate variability. In this field it connects ocean observations to coastal flooding and to seasonal climate.
Ocean science studies the physics, chemistry, biology and geology of the oceans and coasts. It informs bilindbûna asta deryayê, bilindbûna ava behrê ya bahozê, marine heatwaves, acidification and fisheries change, all of which affect coastal populations and trade. In climate and hazards and disaster and crisis, ocean projections guide coastal defence, port planning and fisheries management. They link marine hazards to food security, shipping routes and coastal economies. The canonical description is on STEM Commons.
Tide gauge records are separated into tide, surge and mean sea level, and extremes are combined with sea-level projections to estimate future lehiya peravê levels.
Sea surface temperatures are compared with a seasonal climatology to detect marine heatwaves and their duration and intensity.
Indices of El Niño and other ocean-atmosphere modes are tracked because they shift rainfall, bahoz and drought probabilities across regions.

No observed data enters this model: it runs on the teaching values set by the controls, to be replaced with a programme’s own evidence.
Li seranserê şeş stûnan, bi pêşengiya Nexus Consortium
Models are checked against tide gauge records, altimetry and in situ profiles. Hindcasts of past storms and heatwaves test predictive skill.
| Kontrol bikin | How it is done |
|---|---|
| Vertical land motion | Tide gauge trends are corrected for land subsidence or uplift where measured |
| Climatology consistency | Marine heatwave definitions state the baseline period and threshold |
| Projection traceability | Sea-level projections are cited with scenario and percentile |
Coastal processes at fine scale and ice sheet contributions to sea level remain uncertain. Observations of the deep ocean and polar seas are sparse.
Assembled from the Nexus Standards area profile Standardên xetera avhewa: the hazards it names, the pergalan 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.
