This Is BMKG's Explanation Regarding Hot Temperatures In The North Sulawesi Region

MANADO - In recent days, hot temperatures have hit the North Sulawesi region (Sulut).

The Coordinator for Observation and Information at the Sam Ratulangi Meteorological Station in Manado, Ben Molle, in Manado explained that the weather with hot temperatures in the North Sulawesi region in the past few days, especially in mid-April 2023, was caused by the wind divergence pattern or the melting of air masses in most of North Sulawesi, which simply had an impact on growth and very small cloud cover occurring in the morning and evening.

"The UltraViolet (UV) Sinar is an electromagnetic wave part of the energy of solar radiation. In general, UV rays that reach the Earth's surface will be influenced by several factors, including the apparent position of the sun and cloud cover (the more clouds, the UV rays that reach the earth's surface will be smaller)," said Ben as quoted by ANTARA, Tuesday, April 25.

Each region in Indonesia has the value of the UV Index as predicted and informed by the BMKG.

Such conditions affect the measurable daily maximum temperature in five BMKG observation locations in North Sulawesi, namely in the range of 32-34 degrees Celsius and 35 degrees Celsius in the archipelago district.

He also explained the recent heatwave news in Indonesia. According to the World Meteorological Organization (WMO), he continued, the heatwave, known as heatwave, is a phenomenon of prolonged hot air conditions for five days or more consecutively, where the maximum daily temperature is higher than the maximum temperature of up to 5 degrees Celsius or more.

This phenomenon of heat waves usually occurs in medium-high latitude areas such as Europe and America.

The dynamics of the atmosphere can occur because of the presence of hot air trapped in an area due to the anomaly of atmospheric dynamics which causes the air flow to not move on a large scale, such as for example there is a high pressure system on a large scale and occurs for quite a long time.

Geographically, Indonesian territory is located around the equatorial region, so it has different atmospheric dynamics characteristics from the medium-high latitude region. In addition, Indonesia also has rapid weather change variability.

With the different characteristics of the atmospheric dynamics, it can be said that in Indonesian territory there is no phenomenon known as heat waves.

"What happens in Indonesian territory is the condition of the daily heat temperature which is generally influenced as in the explanation above," he said.

Based on the results of BMKG observations, the maximum temperature on April 17, 2023 was recorded at 37.2 degrees Celsius, occurring in Ciputat, South Tangerang.

The daily maximum temperature change can occur on a daily time scale depending on weather conditions in an area.

Currently, the North Sulawesi region is still in a transition period with the characteristics of rapid weather changes occurring, where in the morning the weather tends to be sunny and then in the afternoon there can be moderate to heavy rain accompanied by sporadic / uneven lightning and potentially strong winds suddenly.

"People are advised to continue to anticipate such weather conditions. For people who want to get the latest weather information, BMKG opens 24-hour weather information services," he concluded,
