Hawaii From Space



Interesting weather in Hawaii - an animation of IR images during a frontal passage December 4-6, 2007


Interesting weather on Mars! - a NASA animation of Mars Spirit Rover images showing several dust devils racing across the surface. Images were taken on July 13, 2005. Real elapsed time in seconds is shown in the lower left corner



QBO Vizualization - Monthly-mean zonal-mean zonal wind observations from UKMO analyses November 1991-June 1998



Research Interests

Observations and modelling of the global-scale circulation of the atmosphere

Climate modelling and climate change

Meteorology and chemistry of the stratosphere and mesosphere

Atmospheric and oceanic waves and tides

Dynamics of planetary atmospheres



Vortex Visualization

Here is an attempt to visualize the polar vortex as simulated in the GFDL SKYHI General Circulation Model. What is shown is an instantaneous picture of a surface that surrounds the air with low nitrous oxide concentration (in this case low relative to the mean value at each horizontal level). What you see is a Northern Hemisphere projection with the vertical scale marked in potential temperature. The vertical extent shown is from about 10 km to 45 km. The main vase-like sheath outlines the polar vortex, while the ribbons wrapping around the vortex represent air that has recently eroded from the vortex. (for more details)

Here is my colleague Wataru Ohfuchi during a visit he made to IPRC back in 2005.

In 2006 Wataru and I edited a book on high resolution numerical simulation (for more information)



Here is a view of near-instantaneous precipitation from a high-resolution global model run at the ESC. This is a photo taken while an animation produced in collaboration with the Bishop Museum in Honolulu is projected onto a large sphere in their "Science on the Sphere" exhibit hall.



In 2006 & 2007 I participated in Hawaii Public Radio shows featuring discussions of environmental issues and research efforts relevant to Hawaii.
