THE CLIMATE OF THE CANARY ISLANDS BY ANNUAL CYCLE PARAMETERS
Annual cycle parameters (ACP) provide a global climatology of annual land surface temperature (LST) based on daily 1 km MODIS observations. These are based on a simple model of the annual temperature cycle and allow estimating LST patterns under largely cloud-free conditions for every day of year....

| Summary: | Annual cycle parameters (ACP) provide a global climatology of annual land surface temperature (LST) based on daily 1 km MODIS
observations. These are based on a simple model of the annual temperature cycle and allow estimating LST patterns under largely
cloud-free conditions for every day of year. Further, they deliver measures for the LST variability and the frequency of cloud
occurrence. It has been demonstrated, that they reproduce important surface climate characteristics at global and urban scale but
their ability to reproduce topo-climates has yet to be studied in detail. In this paper their suitability to investigate climatic variability
at km scale were studied at the case of the Canary Islands (Spain). This Archipelago, has a very stable climate dominated by the
Azores high and the trade wind belt, but shows a large number of micro-climates ranging from arid hot climates to cold climates. It
was found that ACPs are a relevant source of climatic information at km scale in complex orography. Specifically, known features
such as subsidence inversion, the resulting sea of clouds, the strong differentiation in precipitation between the flat and high islands,
as well as the northern and southern slopes at the latter were clearly visible in the parameters. |
