Weather may remain dry across country
Weather may remain mainly dry with temporary partly cloudy skies across the country, with chances of drizzles at one or two places in Barishal, Khulna divisions and Cumilla region.
Moderate to thick fog may occur at places over the river basins and light to moderate fog may occur elsewhere over the country – from late night till tomorrow morning, said the regular bulletin of BMD.
Night and day temperatures may fall slightly over the country.
The lowest temperature in the country was recorded at 12.85 degrees Celsius in Feni and the highest temperature was recorded at 32.3 degrees Celsius in Cox’s Bazar.
UN highlights key role of weather balloons in climate monitoring
Weather balloons play an important part in a vast, intricate global observation system, providing vital information for climate monitoring and forecasters, the UN World Meteorological Organization (WMO) said Friday.
On the heels of recent news reports about Canada and the US shooting down several flying objects, including an alleged Chinese "spy balloon," inside their borders, the UN agency said weather balloons provide just a tiny fraction of the millions of observations gathered worldwide daily.
On Thursday, US President Joe Biden made public remarks after days of speculation over three unmanned aerial objects shot down last weekend by the US military, saying that they were "most likely tied to private companies, recreation or research institutions."
More than 50 satellites collect information from space, and about 400 aircraft operated by some 40 commercial companies gather input from the skies, the WMO said.
From the seas, about 400 moored buoys, 1,250 drifting buoys, and 7,300 ships provide help in addition to 10,000 automated and land-based observing stations across the planet.
Every day, free-rising latex balloons are released simultaneously from almost 900 locations worldwide. Nearly 1,000 balloons gather daily observations that provide input in real-time.
The valuable information gathered contributes to computer forecast models, local data for meteorologists to make forecasts and predict storms, climate monitoring and data for research to better understand weather and climate processes.
Computer forecast models that use weather balloon data are used by all forecasters worldwide, the WMO said.
Equipped with battery-operated radiosondes that capture observations, the floating information collectors are airborne for around two hours.
They measure pressure, wind velocity, temperature and humidity from just above the ground, to heights of up to 35 kilometres, sustaining temperatures as cold as -95°C (-139°F), before bursting and falling back to the Earth under a parachute.
Playing a key role as part of the world's global observing network for decades, they are the primary source of above-ground data.
Their valuable input feeds the Global Observing System, among the most ambitious and successful instances of international collaboration of the last 60 years, the UN agency said.
The system consists of individual surface and space-based observing systems owned and operated by a plethora of national and international agencies.

Warm start to 2023 breaks records in Europe: UN
The unusually warm conditions in Europe that marked the festive season broke records in several countries on the continent, on New Year's Eve and New Year's Day, the UN weather agency said.
The UN World Meteorological Organization (WMO) linked the record-breaking heat to widely accepted peer-reviewed scientific data from the UN Intergovernmental Panel on Climate Change (IPCC) indicating that the frequency of cold spells and frost days "will decrease."
"Strong declines in glaciers, permafrost, snow cover extent, and snow seasonal duration at high latitudes or altitudes are observed and will continue in a warming world," the IPCC said.
According to the UN agency, New Year temperatures soared above 20 degrees Celsius in many European countries, even in central Europe.
National and many local temperature records for December and January were also broken in several countries, from southern Spain to eastern and northern parts of Europe, the WMO said.
At Spain's Bilbao airport, a reading of 25.1 degrees Celsius on January 1 smashed the previous all-time record established 12 months earlier, by 0.7 degrees Celsius.

And in the eastern French city of Besançon, which is usually chilly at this time of year, temperatures hit a new all-time high of 18.6 degrees Celsius on New Year's Day, 1.8 degrees Celsius above the previous record, dating back to January 1918.
In the German city of Dresden, the 1961 New Year's Eve record of 17.7 degrees Celsius was left trailing by the 19.4 degrees Celsius reading taken on December 31, 2022, just as Poland's Warsaw residents saw in the new year with temperatures peaking at 18.9 degrees Celsius, a staggering 5.1 degrees Celsius higher than the previous all-time record for January, from 1993.
Further north, on Denmark's Lolland island, 2023 started with a new high of 12.6 degrees Celsius, overtaking the 12.4 degrees Celsius record set in 2005.
The WMO attributed the warm spell in Europe to a high-pressure zone over the Mediterranean region which encountered an Atlantic low-pressure system.
Their interaction induced a strong south-west flux that brought warm air from north-western Africa to middle latitudes, the UN agency said, adding that this hotter-than-normal air was further warmed when passing the North Atlantic, due to a higher-than-normal sea surface temperature.

Highlighting the influence of warmer sea waters on weather patterns, the WMO noted that in the eastern North Atlantic, sea surface temperature was 1 to 2 degrees Celsius higher than normal, and near the coasts of Iberia, even more.
All this caused record-breaking heat in several European countries on New Year's Eve and New Year's Day, the WMO said.
The weather extremes experienced in Europe are projected to carry on increasing, the WMO said, as it referenced a recent analysis published with "high confidence" by the IPCC.
"Regardless of future levels of global warming, temperatures will rise in all European areas at a rate exceeding global mean temperature changes, similar to past observations," the IPCC said.
