The various precipitation types formed within winter storms (such as snow, wet snow and freezing rain) often lead to very hazardous weather conditions. These types of precipitation often occur during the passage of a warm front as a warm air mass ascends over a cold air mass. To address this issue further, we used a one-dimensional kinematic cloud model to simulate this gentle ascent (≤10 cm/s)...

Significant summer warming over the eastern Antarctic Peninsula in the last 50 years has been attributed to a strengthening of the circumpolar westerlies, widely believed to be anthropogenic in origin. On the western side of the peninsula, significant warming has occurred mainly in austral winter and has been attributed to the reduction of sea ice. The authors show that austral fall is the only...

15 Arctic climate has experienced major changes over the past millennia that are not fully 16 understood in terms of their controls and seasonality. Stable-data from ice wedges in 17 permafrost provide unique information on past winter climate. Recently, an ice-wedge 18 record from the Lena River Delta suggested for the first time that Siberian winter 19 temperatures increased throughout the Ho...

North American seasonal migrants, who are usually retired, typically live in recreational vehicle/mobile home park communities in the southern U. S. during the winter months. This study examines the importance of specific park characteristics in the park selection process and uses the case of winter migrants in south Texas to demonstrate how parks may use a modified approach of importanceeperfo...

Avian species diversity and territory location are often associated with sharp forest edges, or boundaries. However, our understanding of behaviours underlying avian distribution near forest boundaries, especially species with large home ranges, remains poor. In a two-year study, we measured chickadee flock movements in forests at 0–300 m from boundaries in an agricultural landscape near Edmont...

It is a fact that crops growth conditions vary greatly in the same field. Provisionally actual growth conditions are made up of many components, i.e. variation of natural conditions (climate & soil), results of effect of machinery on soil ( soil compaction) and unfavourable conditions for plant growing. In Estonia rather widely used ATV are causing remarkable damage to landscapes. All collected...
