YOGYAKARTA Do you know what a day without rain (HTH) is? This term often appears in weather forecast reports and seasons issued by the Meteorology and Geophysics Agency (BMKG).
For example, in a weather report at the end of May, BMKG said that most areas of Java, Bali, and Nusa Tenggara had experienced days without rain for 21-30 days or more, with dry states starting to enter Indonesian territory, especially in the southern part of the Equator.
According to the BMKG, it is estimated that most areas of Java, Bali, and Nusa Tenggara will enter a dry period in the next 3 basics, with drought conditions dominating until the end of September, reported VOI.
From the weather forecast report, it can be understood that a day without rain can occur when a region is in the middle or will enter the dry season.
So, what is a day without rain? To find out the answer to this question, see an explanation of the day without rain in the following review.
According to the official BMKG website, the day without rain is a day when there will be no rain at all or day where the rain is less than or below 1 millimeter (mm) in a row. The number of days without rain is calculated to be delayed starting from the last day of observation until it rains at least 1 millimeter per day.
Days without rain can also be called dry days. The very short HTH category lasts for 0-5 days without rain. While the very long category of HTH occurs 31-60 consecutive days without rain.
In more detail, the following are the category of days without rain according to BMKG:
Meanwhile, what is meant by a series of days without rain (dry spell) is the number of days without rain or dryness that occur in a row that is not interspersed by rainy days or wet days.
BMKG routinely releases reports related to dry season analysis, including monitoring of days without rain that occur in a number of areas in Indonesia.
Based on the release of the BMKG at the end of last May, several regions in Indonesia have the potential to experience drought during the dry season. Especially the areas of Java, Bali, and Nusa Tenggara that have experienced long HTH, namely 21-30 days.
"The area with the potential for very low monthly rainfall, less than 50mm per month, such as most of Sumatra, Java Island, West Kalimantan, North Kalimantan, Bali, Nusa Tenggara, parts of Sulawesi Island, and parts of Maluku and Papua, requires special attention for mitigation and anticipation due to drought," said Head of BMKG Dwikorita Karnawati.
Monitoring hotspots show the onset of several initial hotspots in areas prone to forest and land fires (karhutla), require special attention to anticipate fires throughout the dry time. BMKG shares technical recommendations including the implementation of weather modification technology for reservoir filling in dry areas and wets land prone to forest and land fires.

Dwikorita appealed to local governments to maximize rainwater harvesting efforts through reservoirs, retention ponds, infiltration wells, and others. BMKG also wants to coordinate with the Minister of Agriculture and the Governor of the Affected Province to adjust the pattern and time of planting agriculture.
