Weather, with its ever-changing dynamics, has a profound impact on our daily lives, shaping our routines and influencing the environments we inhabit. In this exploration, we unravel the complexities of current weather systems, focusing on two key players: the cyclonic circulation over the southeast Arabian Sea and the western disturbance traversing the middle tropospheric westerlies.
Cyclonic Circulation in the Arabian Sea: The lower tropospheric levels are currently hosting a cyclonic circulation over the southeast Arabian Sea. This atmospheric system plays a pivotal role in shaping the weather conditions in the surrounding regions, with its effects reaching far and wide.
Western Disturbance’s Traverse: In the middle tropospheric westerlies, a trough known as the Western Disturbance extends along Long. 52°E to the north of Lat. 25°N. This disturbance brings with it a host of weather changes, impacting areas from south Tamil Nadu and Kerala to Mahe and Lakshadweep.
Forecast and Warnings:
- December 21st: Light to moderate rainfall is anticipated at isolated places, accompanied by isolated thunderstorms. Lightning is very likely over south Tamil Nadu, Kerala, Mahe, and Lakshadweep on this date, with a significant decrease expected thereafter.
- December 22nd-24th: Isolated light rainfall and snowfall are on the horizon over Jammu-Kashmir-Gilgit-Baltistan-Muzaffarabad and Himachal Pradesh. Additionally, on December 23rd, these weather conditions are expected over north Punjab, north Haryana, and Uttarakhand.
- Next 5 Days: The remaining parts of the country are forecasted to experience no significant weather changes during the next five days.
Dense Fog Warning:
- Dense fog is likely in isolated pockets over Punjab, Haryana, Assam, and Meghalaya. Moreover, the northeastern regions of Nagaland, Manipur, Mizoram, and Tripura can expect dense fog in the morning hours over the next three days.
Minimum Temperatures Forecast:
- Over the next 24 hours, there is no significant change in minimum temperatures expected over Northwest, Central, and East India. However, a subsequent rise of 2-3°C is foreseen thereafter.
Understanding and staying informed about these weather systems and forecasts are crucial for individuals and communities to prepare for and adapt to the upcoming atmospheric conditions.
