| Zusammenfassung |
| This paper presents a detrending method that eliminates the potential bias in current
spatial interpolation products caused by measurements unevenly distributed in time.
The method estimates a trend component in addition to the spatial structure and
has been implemented within the Data Interpolating Variational Analysis (DIVA)
analysis tool. It is used to produce monthly climatologies of the Black Sea Cold
Intermediate Layer (CIL) cold content while recognizing its seasonal and inter-annual
variability.
The analysis of the inter-annual trends, given as a by-product of the method, allows one to
relate the CIL inter-annual variability to the cumulated air temperature and wind curl
anomalies, resolving 79% of its variation and providing a partial (29%) predictive ability for
the CIL intensity in the year to come. |
