I believe in your context, tiempos refers to time, not weather.
Does the following fit your context?

In the field of climatology, SEE:

the minimum Arctic sea ice concentration time period...

The simulation of fluctuating concentration time-series in atmospheric dispersion ('climatology' of fluctuations)

1-hr ozone concentration time series data ...

The speaker noted that another method of locating emission sources is to study the concentration time series, since the effect of an increasing distance-to-source on this signal is to reduce peaks and increase characteristic length scales of variation. (EPA Center on Airborne Organics: 1996 Summer Symposium Report)

ALSO:
CONCENTRATION TIME : The period of time required for storm runoff to flow from the most remote point of a catchment or drainage area to the outlet or point under consideration. Concentration time varies with depth of flow and channel condition.

SEE:
The concentration time-series will be made available to all modeling groups for improving emissions factors for dust and the other components

At a location like Zhenbeitai, on the edge of the Mu Us Desert and the Loess Plateau, what is the CLIMATOLOGY OF CONCENTRATION-RELATED PROPERTIES? This information is needed to know how to model these radiative effects and to determine the appropriate time averaging of aerosol properties so that modelers can improve the aerosol treatments in climate
and chemistry models. Furthermore, the time series data on spectral optical depth and integral solar radiation will aid in constraining satellite aerosol retrievals: 1) TOMS (for total ozone and AOD), 2) CERES (surface radiation budget from TOA broadband radiation), and 3) high-resolution instruments on Terra (AOD).
