But a new Philippine study\u2014the first of its kind\u2014has found that the country&#8217;s hottest days are, in fact, more likely to produce hail. The paper is <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/link.springer.com\/10.1007\/s13143-025-00409-4\" target=\"_blank\">published<\/a> in the <i>Asia-Pacific Journal of Atmospheric <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a>s<\/i>.<\/p>\n<p>Hailstorms are so few and far between in the Philippines that, even in an age of pervasive <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">social media<\/a> updates, they are still met with amazement and astonishment.<\/p>\n<p>&#8220;Most people are surprised when hail h<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>ens because it is relatively rare in the Philippines,&#8221; said Dr. Lyndon Mark P. Olaguera, senior author of the study. &#8220;Many take photos or videos and share them online. Some are scared since it&#8217;s unusual, while others just treat it as a strange kind of rain. People usually explain it as part of strong thunderstorms, and some interpret hail as a warning or sign of climate change.&#8221;<\/p>\n<p>The largest hailstones ever recorded in the country fell in Cabiao, Nueva Ecija, on May 8, 2020. These ice balls reportedly reached up to 5 centimeters in diameter, larger than golf balls. High surface temperatures on that day provided the ideal conditions for temperature-driven air movements or convection. Using satellite and radar data along with high-resolution weather modeling, the researchers confirmed the presence of strong updrafts and favorable conditions for hailstorms at the time.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Ice_born_from_hot_air\"><\/span>Ice born from hot air<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The counterintuitive connection between heat near the ground and ice falling from the sky is partly explained by a meteorological factor known as convective available potential energy (CAPE), a measure of how much energy is available to fuel rising air.<\/p>\n<p>High CAPE values indicate conditions favorable for convective activity, wherein hot air near Earth&#8217;s surface rapidly rises and carries moisture into towering thunderclouds. Within these clouds, powerful updrafts can carry water droplets high enough into much colder layers of the atmosphere, where they freeze and eventually grow into hailstones.<\/p>\n<p>Also, the presence of dry air in the mid-troposphere can actually increase the likelihood of hailstones surviving to reach the ground. Dry air enhances evaporative cooling, which strengthens downdrafts and accelerates the descent of hail. Because the hailstones spend less time passing through warmer air on their way down, they are less likely to melt completely before hitting the ground.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Groundbreaking_study_of_tropical_ice\"><\/span>Groundbreaking study of tropical ice<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Spanning nearly two decades worth of data, from 2006 to 2024, the Philippine study is the first ever comprehensive analysis of hail occurrences in the country. The researchers found that hail events were most frequent during the dry-season months of March, April, and May\u2014precisely the period when surface temperatures peak and the atmosphere is primed for thunderstorms. Most hailstorms were found to have occurred during the mid to late afternoon, the hottest part of the day.<\/p>\n<p>Interestingly, while Luzon recorded the most hail events overall, relatively larger hailstones were more observed in the Visayas and Mindanao. The study attributes this to the weaker influence of the Southwest Monsoon in those regions, which allows localized convective storms to persist later into the year.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Invaluable_importance_of_citizen_science\"><\/span>Invaluable importance of citizen science<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>For their study, the researchers relied on a wide range of sources\u2014not just instrument data, but also local government records, <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a> media, and geotagged social media posts. This multi-source, crowd-informed approach proved especially valuable given the country&#8217;s sparse ground-based hail detection capabilities. This shows the invaluableness of citizen science and public reporting in monitoring hailstorms and other severe weather hazards.<\/p>\n<p>As climate change increases the likelihood of extreme weather, empowering the public to participate in data gathering may prove essential for the development of early warning systems in the Philippines. Looking ahead, the researchers stress the need to expand the country&#8217;s weather monitoring and forecasting capabilities. They recommend that local disaster preparedness focus not only on typhoons and floods, but also on less familiar hazards which can catch communities off guard\u2014such as tornadoes and waterspouts, as well as hailstorms.<\/p>\n<p>The study &#8220;Spatiotemporal Analysis of Hail Events in the Philippines&#8221; was authored by Marco Polo A.
