The state-variable matrix approach of modern control theory is applied to a multi-input, multi-output meteorological network. The problem of providing suitable controllers to...

The work reported here derives from a cooperative no-cost agreement between the High Altitude Observatory (HAO) of the National Center for Atmospheric Research (NCAR) and the...

In many places, predictions of regional climate variability associated with the El El Niño-Southern Oscillation phenomenon offer the potential to improve farmers' decision...

The composition of meteoric smoke particles in the mesosphere is constrained using measurements from the Solar Occultation For Ice Experiment (SOFIE) in conjunction with models....

Westerly wind trends at 850 hPa over the Southern Ocean during 1979-2011 exhibit strong regional and seasonal asymmetries. On an annual basis, trends in the Pacific sector...

he use of mesoscale modeling to reproduce the power deficits associated with wind turbine wakes in an offshore environment is analyzed. The study is based on multiyear...

Interannual--decadal variability of tropical cyclone (TC) track density over the North Atlantic (NA) between 1979 and 2008 is studied using observations and simulations with a...

To assist the National Science Foundation in meeting the needs of the community of scientists by providing them with the instrumentation and platforms necessary to conduct their...

During the winter of 2015, there was a strong El Nino (ENSO) event, resulting in significant anomalies for meteorological conditions in China. Analysis shows that the...

This guides serves as an addendum to NCAR Graphics Generic Package Installer's Guide.

The variation of the vector magnetic field along structures in the solar corona remains unmeasured. Using a unique combination of spectropolarimetry and stereoscopy, we infer...

In a previous study, the authors showed that the intensification process of a numerically simulated axisymmetric tropical cyclone (TC) can be divided into two periods denoted by...

To evaluate the utility of trajectory analysis in the tropical upper troposphere/lower stratosphere, Lagrangian predictions of ozone mixing ratio are compared to observations...

To help understand the large disparity in the results of circulation modeling for the atmospheres of Titan and Venus, where the whole atmosphere rotates faster than the surface...

Widespread moderate turbulence was recorded on three specially equipped commercial airline flights over northern Kansas near the northern edge of the extensive cirrus anvil of a...

Radiosonde descent profiles have been available from tens of stations for several years now - mainly from Vaisala RS41 radiosondes. They have been compared with the ascent...

The middle thermosphere from ~150 to 250 km is characterized by rapid increase in temperature with altitude and rapid ionization. The entire thermosphere is believed to be home...

Arctic Ocean warming and sea ice loss are closely linked to increased ocean heat transport (OHT) into the Arctic and changes in surface heat fluxes. To quantitatively assess...

Airborne radar reflectivity measurements at frequencies of 9.6 and 94 GHz, with collocated, in situ particle size distribution and ice water content measurements from the Cirrus...

Accurate models are important to predict how global climate change will continue to alter plant phenology and near-term ecological forecasts can be used to iteratively improve...
