Abstract:
... The severe convective storm (SCS) events that affect Tehran during spring and early summer have potential to cause devastating effects. To study SCSs in Tehran, a climatological analysis is carried out using surface data of Tehran's Mehrabad station from 1961 to 2015 and the NCEP/NCAR reanalysis data to compute the large-scale and the local stability indices. Based on the maximum wind speed, the e ...

Abstract:
... Decadal changes in the teleconnection between the central tropical Pacific and the Southern Hemisphere extratropics are studied using the NCEP–NCAR reanalysis data. Concurrent and lagged relationships show that teleconnection strength in austral spring was weak (strong) before (after) 1996/1997. This decadal change coincides in time with the climate regime shift in the Pacific in the 1990s known f ...

Abstract:
... To adapt to an ocean environment of changing wave period, a novel point-absorber concept is proposed: a fully-enclosed Dual Mass-Spring-Damper (DMSD) floater system that has an internal mass and spring so that its resonance frequency can be varied by changing the movable internal mass and spring. In a waterproof floater, this one-degree-of-freedom heaving energy converter can float or be submerged ...

Abstract:
... Observational evidence showed that the leading mode of precipitation variability over the tropical Pacific during boreal spring experienced a pronounced interdecadal change around the late 1990s, characterized by a precipitation pattern shift from an eastern Pacific (EP) type to a central Pacific (CP) type. The distinct impacts of such a precipitation pattern shift on the extratropical atmospheric ...

However, most frameworks mainly consider the process complexity of the model, and few of them consider the spatial complexity. In this paper, we investigated the appropriate model structure for a karst catchment from the aspect of spatial complexity. The purpose is twofold: (1) to investigat ...

The results showed that during periods of water rising in jam-free years, water levels were distributed in a random manner, in accordance with an exponential (Poisson-like) function. In contrast, water-level distributions during periods preceding ice-jams ...

Hibernating as an imago inside a seed, it can withstand mild winters, only to emerge in spring, spawning up to five generations during spring and summer. Coccotrypes dactyliperda is a comparatively long-lived Coleoptera species that has proven to be highly adaptable at infesting seeds of a wide r ...

Abstract:
... We analysed 25 conspecific egg ejection events from a large sample of nests (n = 762) of three passerine species. In two species, most of the events could not be explained by intraspecific brood parasitism or nest sanitation behaviour. At least some of these cases were behavioural responses to unfavourable weather conditions in the spring of 2017. We conclude that clutch size adjustment through eg ...

However, it has previously been reported that translocated individuals have lower demographic performance than their wild-born conspecifics, due to management and individual factors (such as release conditions or age). Here, we study six breeding parame ...
