Detecting climate signals in populations across life histories
Climate impacts are not always easily discerned in wild populations as detecting climate change signals in populations is challenged by stochastic noise associated with natural...- publication PDF

Atmospheric rotors and severe turbulence in a long deep valley
The conceptual model of an atmospheric rotor is reexamined in the context of a valley, using data from the Terrain-Induced Rotor Experiment (T-REX) conducted in 2006 in the...- publication PDF

Tropopause‐Level NOx in the Asian Summer Monsoon
Deep convection within the Asian summer monsoon (ASM) transports surface level air into the upper troposphere-lower stratosphere (UTLS). This work aims to understand the...- publication PDF

Cancellation exponents in helical and non-helical flows
Helicity is a quadratic invariant of the Euler equation in three dimensions. As the energy, when present helicity cascades to smaller scales where it dissipates. However, the...- publication PDF

The intraseasonal and interannual variability of Arctic temperature and speci...
Temperature and humidity inversions are common in the Arctic's lower troposphere, and are a crucial component of the Arctic's climate system. In this study, we quantify the...- publication PDF

Representation of boundary layer moisture transport in cloud-resolving models
One of the important roles of the PBL is to transport moisture from the surface to the cloud layer. However, how this transport process can be accounted for in cloud-resolving...- publication PDF

Sensitivity of mountain wave drag estimates on separation methods and propose...
Internal gravity waves (GWs) are ubiquitous in the atmosphere, making significant contributions to the me-soscale motions. Since the majority of their spectrum is unresolved in...- publication PDF

Characteristic scales of complexity and coherence within interplanetary coron...
Many aspects of the 3D structure and evolution of interplanetary coronal mass ejections (ICMEs) remain unexplained. Here, we investigate two main topics: (1) the coherence scale...- publication PDF
