International Journal of Climatology, EarlyView.This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

A SPECIAL FOEHN CASE IN NORTH-EASTERN APUSENI MOUNTAINS [PDF]
Aerul şi Apa: Componente ale Mediului, 2016 The paper presents a case study for the 9-10 January 2015 period, when foehn processes were occurred on the eastern slope of the Apuseni Mountains. With a view to establishing the synoptic context in which the phenomenon was manifested, an analysis of ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.A theory for the interaction between a boundary layer and a low mountain is used to provide estimates of the turbulent orographic form drag, upward‐propagating mountain gravity‐wave drag, and trapped lee‐wave drag (case shown in the figure). After reviewing briefly how these processes are represented in weather and climate models, we propose a ...

Observations and numerical simulations of a valley‐exit wind in the Alpine Bolzano basin
Quarterly Journal of the Royal Meteorological Society, EarlyView.The evolution and spreading of the nocturnal valley‐exit wind flowing from the Isarco Valley into the Bolzano basin, in the Italian Alps, are found to be influenced by the basin temperature stratification. Measurements and high‐resolution simulations show that a cold‐air pool favors an upward trajectory of the flow at the exit of the valley.

Outracing a National Level Model Racing Car Champion: A Hybrid Model‐Based Data‐Driven Approach
Journal of Field Robotics, EarlyView.ABSTRACT This paper discusses lap time optimization, focusing on a single lap without considering opponents in autonomous racing. The paper presents a control and optimization architecture composed of a model‐based low level controller and a higher level iterative learning algorithm with the goal of obtaining the fastest qualifying lap in autonomous ...

The riddles of foehn - introduction to the historic articles by Hann and Ficker
Meteorologische Zeitschrift, 2012 Two key papers on the topic of foehn are introduced. The first one, published in 1885 by Julius Hann, discusses the history of the “thermodynamic foehn theory, and the role of the various scientists who contributed to its evolution.

Weather, EarlyView.The English language is a gargantuan, gluttonous beast. It has become extraordinary among its peers in its powers of assimilation – such that we rarely consider the diverse origins of the words we use. In this two‐part paper, we will explore these origins, including the Pontic‐Caspian steppe, the British Empire, latinophone scientists and a TV show. We

A protracted phenology: Post‐diapause larval development of a threatened butterfly
Insect Conservation and Diversity, EarlyView.Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.

The Foehn Effect on Mortality in Asturias [PDF]
, 2017 The Foehn Effect is a phenomenon that occurs when two weather variables coexist: southerly wind and a significant increase in temperature. This can affect the health of the wearhersensitive people.

Foehn jets over the Larsen C Ice Shelf, Antarctica [PDF]
, 2014 Previously unknown foehn jets have been identified to the east of the Antarctic Peninsula (AP) above the Larsen C Ice Shelf. These jets have major implications for the east coast of the AP, a region of rapid climatic warming and where two large sections ...
