On the animation above: The left column show the past (1.5 degree colder) climate, second column the current climate. The remaining two columns show the same weather in a +1.5 and +3.0 degree warmer world (compared to current climate). For the +3.0 degree warmer world, we selected a variant with enhanced drying. As you can see in the animation the weather patterns (contours show mean sea level pressure in hPa) within the domain generally match very well, but adjustment to the cooler/warmer initial and (lateral) boundary conditions occurs, because the model (in this case RACMO, used at 12km) is free to evolve in the interior of the domain. As a consequence further thermodynamic and more small-scale dynamic adjustments occur, which leads to showers intensifying (or not), soil drying out more substantially etc. In the near future we intend to extend this imagery by including simulations with HCLIM at high resolution (2.km). This resolution is necessary to better capture the shower development for example.
Images above show timeseries of temperature (left) and precipitation (right). Top-left panel is a time-series for the average temperature within the Netherlands as a 3-hourly time-series. The lower-left panel shows the temperature response (PGW-CTL, thin lines show spatial max wrt to the CTL domain-average; in future we will replace this by max wrt max CTL). The top-right figure shows rolling 12-hour precipitation sum averaged over subdomain NWeur (covering a.o the Netherlands).
