Observed Low Level Jets Associated with Typhoon Higos (0221) over the Kanto Plain

Summertime Low-Level Jets Over the Great Plains

A low-level jet (LLJ) is a wind speed maximum that occurs in the lowest few km of the atmosphere. The frequency of LLJ development over the United States is documented climatologically by Bonner (1968), indicating that the Southern Great Plains Cloud and Atmospheric Radiation Testbed (CART) site of the Atmospheric Radiation Measurement (ARM) Program is situated within the region of maximum LLJ ...

Global Precipitation Extremes Associated with Diurnally Varying Low-Level Jets

Extreme rainfall events have important societal impacts: for example, by causing flooding, replenishing reservoirs, and affecting agricultural yields. Previous literature has documented linkages between rainfall extremes and nocturnal low-level jets (NLLJs) over the Great Plains of North America and the La Plata River basin of South America. In this study, the authors utilize a 21-yr, hourly gl...

Ground uplift related to permeability enhancement following the 2011 Tohoku earthquake in the Kanto Plain, Japan

We investigated the post-seismic surface displacement of the 2011 Tohoku earthquake around the Kanto Plain (including the capital area of Japan), which is located approximately 400 km from the epicenter, using a global positioning system network during 2005–2015 and persistent scatterer interferometry of TerraSAR-X data from March 2011 to November 2012. Uniform uplift owing to viscoelastic rela...

Climatology of nocturnal low-level jets over North Africa and implications for modeling mineral dust emission

[1] This study presents the first climatology for the dust emission amount associated with Nocturnal Low-Level Jets (NLLJs) in North Africa. These wind speed maxima near the top of the nocturnal boundary layer can generate near-surface peak winds due to shear-driven turbulence in the course of the night and the NLLJ breakdown during the following morning. The associated increase in the near-sur...
