Despite the significant correlations between most of the geochemical weathering indices and Soil Taxonomic Classes (Vogt index had the highest correlation coefficient (r = − 0.74)), these indices represented lower weathering intensity in more developed soils.
The steady-state concept is based on feedbacks between soil thickness and weathering at the base of the regolith, such that (sometimes after an optimal or threshold thickness is achieved), thicker soils lead to lower weathering rates (and vice versa).
The chemical index of alteration (CIA) is the most suitable WI, whereas Ca-free CPA is more easily biased by salinity variations of topsoils at sites with negative water balance, thus pretending lower weathering intensities.
Our results showed that sericite on plagioclase and biotite chloritization, that represent inherited features formed during late-stage hydrothermal alteration of granitoid rocks, may cause an overestimation of the real degree of weathering of primary mineral grains under meteoric conditions, especially in lower weathering grade classes.
The advent of some satellite missions, ground-based instrumentation, and the development of whole atmosphere models has led to a paradigm shift during the CAWSES period that highlights the importance of the lower atmosphere (weather, stratosphere, etc). in the coupling of the atmosphere.
These longer periods in CO2 are suggestive of forcing from the lower atmosphere weather.
We compare hillslope and catchment-wide weathering fluxes with modern stream cation flux, and show that high relief, bare-rock slopes exhibit much lower chemical weathering rates despite higher physical erosion rates.
The waves are the only lower-atmosphere weather that can penetrate the stratosphere and alter ozone patterns, and in the Southern Hemisphere, the waves have been exceptionally strong this year.
Except that the decibel levels were a little lower and the weather behaved itself.
Besides lower temperatures, the weather service predicted more storms and greater precipitation in the Northeast.
