Cloud Streets

GEOS-5 modeled clouds at 3.5-km global resolution on January 2, 2009 capturing cumulus cloud streets off the coast of Asia and North American and cloud vortex streets moving off the Aleutian Islands through the Gulf of Alaska.

Madden-Julian Oscillation Planetary Rainfall Pattern

15-day high spatial- and temporal-resolution simulations of the Madden-Julian Oscillation in May 2002, showing that the westward movement and intensification are modulated by a semi-diurnal cycle.

Tropical Cycle Forecasts

Four 10-day formation forecasts of six tropical cyclones (TC) associated with the westward-propagating Madden-Julian Oscillation (MJO) in May 2002, including two pairs of twin TCs in the Indian Ocean, super-typhoon Hagibis in the West Pacific Ocean and Hurricane Alma in the East Pacific Ocean.

Flux Transfer Event Formation at the Magnetopause

A 600x600 pixel field topology map near a flux transfer event formation at the magnetopause in a global hybrid magnetohydrodynamic simulation dataset, showing 5 topological classes of magnetic field lines. Red pixels correspond to solar wind field lines, blue to magnetosphere field lines, green to northern ionosphere open field lines, yellow to southern ionosphere field lines, and white to lines that end at a field null.

Prediction of Cyclone Nargis (2008)

A 7-day prediction of very severe cyclonic storm Nargis (2008) showing that its formation can be predicted 5 days in advance. Experiments suggest that the following processes and their hierarchical multiscale interactions led to the formation of TC Nargis: 1) a westerly wind burst and equatorial trough, 2) an enhanced monsoon circulation with a zero wind shear line, 3) good upper-level outflow with anti-cyclonic wind shear between 200 and 850 hPa, and 4) low-level moisture convergence.
