HSHL05/HSRR04: Region specific climate information for Haaglanden and Rotterdam
The goal of this project was to provide data and information about the current and future climate in the regions Haaglanden and Rotterdam. The focus was on climate effects on people in the area. Potentially affected users were identified as well as their dependency on specific climate factors. An overview was made of the available knowledge concerning temperature, precipitation, drought, wind, sea level rise, etc. in the current and future climate.
Within the two Hotspots excess and shortage of water are important. To assess the impact of the changes in precipitation, region specific climate information was needed. Several projects of the Royal Netherlands Meteorological Institute (KNMI) provided information on regional differences in precipitation patterns. This information was used to improve the assessment of the impacts.
There was also a high demand for information on extreme temperatures in urban areas in the Haaglanden and Rotterdam areas. Due to the Urban Heat Island effect (UHI effect) the temperature in urban areas is higher than in rural areas. During heat waves this can lead to thermal stress resulting in more deaths, decreased productivity etc. Based on literature and third party measurements this project quantified the UHI effect under different weather conditions in a quickscan. Where possible, the effect of adaptation measures was estimated.
