Decadal climate prediction: An update from the trenches
This paper provides an update on research in the relatively new and fast-moving field of decadal climate prediction, and addresses the use of decadal climate predictions not...- publication PDF

Characterizing the uncertainty and assessing the value of gap-filled daily...
Almost all daily rainfall time series contain gaps in the instrumental record. Various methods can be used to fill in missing data using observations at neighboring sites...- publication PDF

Characteristic scales of complexity and coherence within interplanetary...
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

A quantile-conserving ensemble filter framework. Part I: Updating an...
A general framework for deterministic univariate ensemble filtering is presented. The framework fits a continuous prior probability density function (PDF) to the prior ensemble....- publication PDF

The topology and behavior of magnetic fields emerging at the solar photosphere
The nature of flux emerging through the surface layers of the Sun is examined in the light of new high-resolution magnetic field observations from the Hinode space mission. The...- publication PDF

Modeling bubbles and dissolved gases in the ocean
We report on the development of a bubble concentration model and a dissolved gas concentration model for the oceanic boundary layer. The bubble model solves a set of...- publication PDF

The Craig-Sneyd analytic solutions to the Parker problem
This paper follows up on the conclusion by Craig and Sneyd (2005) that the solutions to a linearized magnetostatic problem are counterexamples to the magnetostatic model of...- publication PDF

Performance bounds for particle filters using the optimal proposal
Particle filters may suffer from degeneracy of the particle weights. For the simplest "bootstrap" filter, it is known that avoiding degeneracy in large systems requires that the...- publication PDF

High ice water content conditions associated with wintertime elevated...
Aircraft flying through areas of high ice water content (HIWC) can experience engine damage and/or failure. HIWC is typically associated with convection and the microphysical...- publication PDF

Novel measures for summarizing high-resolution forecast performance
In ascertaining the performance of a high-resolution gridded forecast against an analysis, called the verification set, on the same grid, care must be taken to account for the...- publication PDF

Ensemble-based forecast uncertainty analysis of diverse heavy rainfall events
This study examines widespread heavy rainfall over 5-day periods in the central and eastern United States. First, a climatology is presented that identifies events in which more...- publication PDF

Recent tropical expansion: Natural variability or forced response?
Previous studies have documented a poleward shift in the subsiding branches of Earth's Hadley circulation since 1979 but have disagreed on the causes of these observed changes...- publication PDF
