Weather forecasters told the Los Angeles Times the meteorological event was the result of a rare combination of cold air from Utah moving over the Southwest and a low pressure system from Baja, California.
When deaths occurred as a result of meteorological disasters resulting in the collapse of a bridge, wall, bungalow, stable, terrace, bank, house, or flooding causing collapse of a house and/or road, these deaths were all combined in the category of structural collapse.
The use of the reallocated meteorological dataset results in a little underestimation, linked with the highest coefficient of determination (0.97). Figure 2E demonstrates that EPIC is not very sensitive to measured or homogenized meteorological input data just in contrast to BETHY/DLR which can be seen in Figure 2A and 2B.
But back to that meteorological event.
A generic system dynamics watershed (GSDW) model was initially calibrated using the onsite meteorological data, resulting in simulated soil moisture values that slightly overestimated observed values.
Snowpack and ablation rates were 10 20% higher during the 2008 and 2009 winters than when running the model for the pre-MPB landscape in 2000 using the same input meteorological data, resulting in almost no difference in the snowcover period.
Meteorological conditions resulted in a very intense secondary low-pressure area moving rapidly at 40 knots into the Bristol Channel, with pressure dropping from 1012 to 962 mb between 0000 hours and 1800 hours.
However, geographic diversity generates meteorological discrepancies, resulting in a complex and difficult analysis.
Rosenberg borrows from the popular book and movie The Perfect Storm, which told how a rare combination of meteorological forces resulted in a monstrously destructive force, to describe the escalation in traffic deaths and injuries in poorer countries.
Gothenburg is a suitable area for such studies, since this region is characterised by a rather large meteorological variability resulting in air mass transport both from clean and polluted areas [ 14, 15, 19].
