Have you ever wondered if one can anticipate and predict the genesis, intensity and tracks of tropical disturbances almost weeks/month in advance with reasonable confidence? While prima-facie, we believed MJO to be the sole tropical wave driving all monsoons, ER which has always been present along with MJO and which moves east->west has actually been the…

“MADDEN JULIAN OSCILLATION” AS THE DRIVER OF SOUTHWEST MONSOON AND “EQUATORIAL ROSSBY” AS THE DRIVER OF NORTHEAST MONSOON RAINFALL
“Truths remain hidden for long while lies easily propagate across weeks, months or even years just like the week-lies” There is always a necessity to unlearn and relearn as new insights emerge. It is in this context; as one reads the title, this post is likely to serve as a revelation to every weather enthusiast/blogger….
WHEELER-KILADIS REPRESENTATION OF TROPICAL WAVES AND THE UTILITY OF HOVMÖLLER DIAGRAM
“Hovmöller said the idea of his construction of meteorological fields using a time-geographic coordinate representation was a mere lucky hit that emerged through creative spurt” Recollect from previous post that climate and weather were compared to low and high frequency atmospheric states respectively, similarly in tropical waves, we have four of them: MJO, ER, CCKW…
CLIMATOLOGY & WEATHER – THE TROPICAL PLANETARY WAVES CONUNDRUM
The wise assert that: “While climate is dictated by the sun and the earth’s axial tilt, weather is dictated by the tropical planetary waves.” While at most instances, the term “climatology” can be construed as governed by the natural law driving atmospheric features and oceanic currents, and the “ensuing weather”just follows the rules written therein, there are plenty of outliers…
