Altimetry is helping seasonal forecast by providing information on the ocean dynamics.

Regions of highest dynamic topography variability are in general regions of highest turbulence. Some few regions also vary a lot, without our precise understanding of the physical origin of such high variability. This is the case in the Solomon Sea.

The South Atlantic Anomaly takes place in the ionosphere, at the magnetic equator. This "anomaly" causes among other things errors on the measurement of the Doris instrument onboard Jason-1.

Analysis of Sea Level Anomalies from merged satellite data, now available for more than ten years, reveals the areas of high eddy activity, the number of eddies during those years, their size and height.

Altimetry can be used for cyclone observation, knowledge and forecasting in a number of different ways. Example is given in the case of the Man-Yi typhoon (July 2007)

In situ measurements especially made during cruises, complete and validate altimetry measurements

Sub-glacial hydrological networks linking the lakes beneath ice in Antarctica between each other appear in altimetry data

The ocean is responding to the seasons, as the atmosphere. Altimetry measured sea surface heights reflects this.

Malaria outbursts are linked to flooded areas. Altimetry continuous monitoring of such areas can be used in epidemiological modelling

The Ierapetra gyre is a Mediterranean oceanic feature. Since 1993, this gyre appeared -- or not -- depending on the periods.

This year El Niño, true to its name (El Niño, i.e., the (Christ) child in Spanish), showed up for Christmas.
