Large - scale changes in savanna vegetation cover may also feed back to
regional rainfall patterns.
A new study released Friday in the journal Science Advances helps clear up a bit of the mystery, by showing that man - made climate change is responsible for most of the change seen in ocean surface temperatures near the equator across Asia, which in turn affect
regional rainfall patterns including the Indian monsoon.
Not exact matches
Since trends in convective
rainfall are not easily detected in daily
rainfall records, or well - simulated by global or
regional climate models, the researchers created a new tool to assess the effects of climate change on
rainfall patterns and trends in dryland areas.
But many of the key questions —
regional variability, changes in the
patterns of
rainfall or statistics of drought, or the interplay of dynamics and thermodynamics in sea ice change — can only be approached using comprehensive models.
The
regional patterns of tropical
rainfall diurnal cycles are specified in the Amazon, Mexico, the Caribbean Sea, Calcutta, Bay of Bengal, Malaysia, and northern Australia.
Can the science reliably predict significant changes in
rainfall patterns at
regional or local levels for say the next 5 decades?
In addition, the
pattern of sea surface temperatures at low latitudes is extremely important for
regional climate variations (shown, for example, by the increased likelihood of heavy winter
rainfall in California when the eastern tropical Pacific warms in El Niño events).
Scientists have also observed that many of Earth's glaciers, ecosystems and other systems are already being impacted by rising
regional temperatures and altered
rainfall amounts and
patterns.
But, I think that nation states are going to engage in unilateral geoengineering to change
rainfall patterns in the next thirty years and that will lead to new
regional conflicts (which we don't need).
The
regional impacts on
rainfall and weather
patterns need to be fully investigated before we go down that road.
These oceanic variations are associated with significant
regional and global shifts in temperature and
rainfall patterns that are evident in the observations.
The National Rural Health Alliance acknowledges that climate change poses a growing risk to the health and wellbeing of people living in
regional, rural and remote communities, through more frequent severe weather events, longer droughts and changes in
rainfall patterns.
