In this paper, we propose a new method based on the detection of jet cores with the aim to
describe the climatological features of the jet streams and to estimate their trends in latitude …

Previous studies have suggested a poleward shift of the zonally averaged jet stream due to
rapid warming over continents. However, the regional characteristics of the change in the jet …

Jet streams, the meandering bands of fast winds located near the tropopause, are driving
factors for weather in the midlatitudes. This is the first study to analyze historical trends of jet …

A new jet stream description, defined as the geostrophic streamline of maximum average
velocity is proposed. An objective algorithm for detecting and tracking the jet has been …

A feature‐based metric of the waviness of the wintertime, Northern Hemisphere polar, and
subtropical jets is developed and applied to three different reanalysis data sets. The analysis …

Previous studies have shown that the mean latitude of the sub-tropical jet streams in both
hemispheres have shifted toward the poles over the last few decades. This paper presents a …

Seasonal to decadal variations in Northern Hemisphere jet stream latitude and speed over
land (Eurasia, North America) and oceanic (North Atlantic, North Pacific) regions are …

Trends in the speed and probability of winter jet stream cores over the Northern Hemisphere
were measured for 1958–2007, and related changes in the thermal structure of the …

Climate models predict a weak poleward shift of the jets in response to continuing climate
change. Here we revisit observed jet trends using 40 years of satellite-era reanalysis …

A simple closed contour object identification scheme has been applied to the zonal mean
monthly mean zonal wind fields from nine global reanalysis data sets for 31 years of the …
