Effects of the COVID-19 pandemic on the use and perceptions of urban green space: An international exploratory study.

Urban green space (UGS) is an essential element in the urban environment, providing multiple ecosystem services as well as beneficial effects on physical and mental health. In a time of societal crisis these effects may be amplified, but ensuring that they are maintained requires effective planning and management - which is a complex challenge given the rapid changes in modern society and the need for continual adaptation. This study aims to identify the drivers that normally attract visitors to UGS, and to assess the effects of social isolation on the usage and perception of UGS during the COVID-19 pandemic.

A new dynamical systems perspective on atmospheric predictability: Eastern Mediterranean weather regimes as a case study.

The atmosphere is a chaotic system displaying recurrent large-scale configurations. Recent developments in dynamical systems theory allow us to describe these configurations in terms of the local dimension-a proxy for the active number of degrees of freedom-and persistence in phase space, which can be interpreted as persistence in time. These properties provide information on the intrinsic predictability of an atmospheric state.

Human-biometeorological conditions and thermal perception in a Mediterranean coastal park.

This study looks at the interrelation of human-biometeorological conditions, physiological thermal stress and subjective thermal perception in the design and use of a new waterfront park in Tel-Aviv, Israel. Our initial assumption was that the park's design would embody a comprehensive response to the area's ever-increasing heat stress and water shortage. However, almost half of it is covered by grass lawns, irrigated with fresh water, while the remaining area is mainly covered with concrete paving, with minimal shading and sparse trees.

Mediterranean weather conditions and exacerbations of multiple sclerosis.

Background: Previous studies provide increasing support for the impact of environmental factors on disease incidence and activity in multiple sclerosis (MS).

Objectives: The purpose of this research was to assess the relationship between the incidence of MS relapses and weather conditions in Israel.

Methods: Clinical data, including occurrence of relapses in 235 patients, during 3 consecutive years (2001-2003) were assessed against the general daily meteorological variables.

The impact of a small lake on heat stress in a Mediterranean urban park: the case of Tel Aviv, Israel.

Field observations of air and surface temperatures, relative humidity, solar radiation and wind were performed in the daytime hours of the warm season around a pond of 4 ha, located in Begin Park, in the city of Tel Aviv, Israel. Observations were carried out at screened meteorological stations on four randomly selected days, all associated with moderate heat stress. Two of them, one representing a warm and dry day, and other, representing a sultry day, are analyzed in detail.
