Marine wind is an example of one variable that changes in response to changing climate conditions. Reconstructions of the historical wind field will help in understanding these changing conditions.
Over the past 100-years, ship-based wind observations
were based on:
(a) the Beaufort
scale
(b) anemometry
Ship observations are spatially
and temporally sparse, and of uneven quality,
but they extend far back in time.
More recently, satellites have provided detailed measurements of the marine wind field. While these are high-quality measurements, they are only available for a short period. As these satellite data sets are extended in the future, they will help us understand wind variations on longer time scales.
LDEO scientists are using the complementary features of
ship and satellite data to obtain the best possible historical reconstructions.
We are working to:
(a) improve our wind reconstructions,
and
(b) extend the reconstruction effort
to other variables (e.g., sea level
pressure,
land temperature), including some variables measured
by satellites
(e.g., sea surface temperature).
