The large-scale environment can have a significant impact on subtropical precipitating systems via the baroclinicity of the environment and the associated dynamical forcings. The degree of baroclinicity is examined using National Centers for Environmental Prediction (NCEP) reanalysis temperature and zonal wind fields over a two-year period for Southeast Texas, yielding classifications of barotropic, weakly baroclinic, and strongly baroclinic for the background environment. Weakly baroclinic environments accounted for half of the days throughout the two-year period. Barotropic environments occurred most frequently during summer and strongly baroclinic environments occurred most frequently in winter, although less often than weakly baroclinic environments. A climatology of storm types, based on dynamical forcing (i.e., weak forcing, drylines, cold fronts, warm fronts, stationary fronts and upper level disturbances) and precipitation structure (i.e., isolated, scattered, widespread, linear, unorganized and leading-line/trailing stratiform), was compiled and compared to the baroclinicity designations. Non-frontal storm types (i.e., weak forcing, drylines and upper level disturbances) are typical of barotropic environments, while frontal storm types (i.e.,warm, cold and stationary fronts) are typical of weakly and strongly baroclinic environments. Storm events and drop-size distributions (DSD) were identified from surface rainfall data collected by a Joss-Waldvogel disdrometer located in College Station, Texas. The DSDs were compared by baroclinicity and storm type. The barotropic DSD is weighted towards the largest drops because of the stronger convection and stratiform precipitation in the weak forcing and dryline storm types, while the strongly baroclinic DSD is weighted towards the smallest drops because of the weaker convection from the warm fronts and stationary fronts. The weakly baroclinic DSD is weighted more evenly towards small and large drops than the barotropic and strongly baroclinic DSDs because of the conflicting microphysical processes in the different storm types. The microphysical processes within the storms vary by storm type and baroclinicity regime, such that the large-scale environment modifies the precipitation characteristics of storms in SE Texas.

The Gudrun storm felled an estimated 75 million cubic meters while Hilde brought about 3,5million cubic meters. In Götaland and southern Svealand was the most affected species sprucewhile pine was the most affected species in the storm of Hilde, Storumans municipality.Although spruce was the most common tree species in both areas. The aim of this study istherefore to examine the factors that led to this. A literature study to obtain data on the stormGudrun have been performed. A direct method (field observations) and indirect methods(interviews) has been used to obtain data relating to the storm Hilde. In the field observationsvisited ten items, here was investigated; species, typ of stands, altitude and wind exposure.Interviews were conducted with eight landowners, where they were to supply informationabout their views on how they was affected by the storm Hilde and the factors that had animpact. The storm damage from Gudrun showed that all investigated factors had an effect onthe extent. Our interviews and observations show that the same factors apart from the altitudehad an impact.
