2. Tree-ring
footprints of drought variability in last ∼300 years
over Kumaun Himalaya, India and its relationship with crop productivity
Ram R. Yadav , Krishna G. Misra, Akhilesh K.
Yadava, Bahadur S. Kotlia, Sandhya Misra
•Standardized Precipitation Index (SPI) developed from Himalayan cedar
chronologies.
•Reconstructed SPI displayed high year-to-year variability.
•SPI significantly correlated with wheat and barley productivity in rainfed
system.
•Historical droughts recorded in reconstruction associated with rabi crop
failures.

3. A dual-tracer approach
to estimate upwelling velocity in coastal Southern California
William Z. Haskell II, , Douglas E. Hammond, Maria G.
Prokopenko
•Using 7Be and 234Th, we estimate upwelling
velocities to be 0.5±0.6 to 2.5±1.3md−1.
•These agree to within uncertainty with the pressure field-based Bakun
Index.
•A heat budget and hydrography suggest that upwelling is driven by wind
stress curl.
