The Monthly ITCZ Central Latitude The ITCZ moves with the Sun and is hard to define.

The Story behind my Paper on the ITCZ and the Hadley Circulation By Andy May It all began eight years ago when I read and reviewed Ronan and Michael Connolly’s first three papers on their ideas about the “molar density intersection” which…

Rains expected as Filipinos visit cemeteries for ‘Undas’ THE Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has issued a weather advisory on Friday, warning that parts of the country may experience cloudy skies and rainfall during the observance of “Undas,” as millions of Filipinos visit cemeteries nationwide. PAGASA noted that the Intertropical Convergence Zone (ITCZ) continues to affect Southern Luzon, the Visayas, […]

Low Pressure Area Inside PAR Unlikely to Become Storm Within 24 Hours, Says PAGASA The Low Pressure Area (LPA 10h) currently located within the Philippine Area of Responsibility (PAR) has a low probability of developing into a full-fledged storm within the next 24 hours, according to the state weather bureau. As of reporting time, the LPA was spotted 260 kilometers east-southeast of Puerto Princesa City, Palawan. PAGASA stated that […]

Flash flood leaves 1 dead, 4 injured after heavy rain in Maasim, Philippines Hours of heavy rainfall associated with the Intertropical Convergence Zone (ITCZ) caused flash floods in Maasim, Sarangani Province, southern Mindanao, on October 6, 2025. At least one person was electrocuted and four others were injured as floodwaters forced the closure of sections of the national highway. Source

Plot of the western hemisphere showing the filtered Kelvin Wave band (blue solid lines indicate upward vertical motion). Note the wave propagating eastward across from 22 Jul to 29 Jul (following the blue arrow).

Not hard to see what is causing the abrupt uptick in convective activity in the Central & East Pacific. A potent Convectively Coupled Kelvin Wave, #CCKW, has been marching eastward, activating the #ITCZ.

This convection may aid #ITCZ breakdown, with 3️⃣ areas being monitored for #TC formation.

I made an error (now corrected) in the original #itcz model that I shared. This is designed to help #GCSE or #nationalgeography visualised the seasonal shift of the ITCZ.
