DO also fluctuated at short-term timescales in response to storms, and DO measured at 15-min intervals could be simulated with a combination of discharge, spring temperature, and specific conductance as explanatory variables.
GEC27R and EUV27R are well correlated over most temporal segments, implying the solar EUV is the primary reason for GEC variations on short-term timescales.
Gartner's recent pace-layered application strategy shows that organisations can accelerate their innovation by choosing an array of systems that support business requirements on long-, medium- and short-term timescales.
But most models have focused on short-term timescales, decades or a few centuries at most, says Anders Levermann, a climate scientist at the Potsdam Institute for Climate Impact Research in Germany and co-author of the new paper.
As a result, particular investigations of the spatial and temporal (especially short term timescale) patterns of the Rb/Sr ratio are necessary before using the Rb/Sr ratios of the lake sediments to study the weathering intensity in the catchment.
Therefore, the increased chemical weathering would also correlate to higher Rb/Sr ratios on short term timescales, e.g. decadal scale.
However, the chemically deposited Sr-bearing mineral is expected to be diluted by the increased proportion of terrigenous detritus when physical loads increases on short term timescales.
Therefore, it is necessary to study the geochemistry of Rb/Sr ratio of lake sediments (especially that on short term timescales) particularly before it is used as an indicator of weathering intensity of the catchment.
On short term timescales (e.g. decadal scale), when physical weathering increases, the chemical weathering intensity in Lake Qinghai catchment is expected to increase because of the increased temperature and precipitation and because of the stronger hydro-rock reaction since more terrigenous particles are involved.
Yet, overall, our data suggest that at both long- and short-term evolutionary timescales, members of SSA subfamily evolved very slowly.
