Consistent trends in dry spell length in recent observations and future projections
We identify global observed changes in dry-spell characteristics that are consistent with future projections and involve common physical drivers. Future projections of longer dry spells in the dry season increase vegetation water stress and can negatively impact perennial vegetation. Lengthening dry...

We identify global observed changes in dry-spell characteristics that are consistent with future projections and involve common physical drivers. Future projections of longer dry spells in the dry season increase vegetation water stress and can negatively impact perennial vegetation. Lengthening dry season dry spells of up to ∼2 days per decade over South America and southern Africa and shortening of similar magnitude over West Africa display a qualitatively consistent pattern to future projected changes under the SSP2-4.5 intermediate greenhouse gas emissions scenario. By combining a range of present-day climate model experiments, recent trends are linked with both natural and human-caused drivers. Longer dry season dry spells over South America are associated with relative warming of North Atlantic sea surface temperatures and amplified warming over land compared with adjacent oceans; both of which are projected to continue under further warming, suggesting a common driver for recent trends and future projections. |
