Rains in Dry Season in Indonesia: The Causes and Tips to Survive

Rains in dry season in Indonesia are a condition where rain continues to fall periodically during the dry season. This condition is called the wet-dry season. In Indonesia, the characteristics of the wet-dry season are hot weather and relatively high rainfall intensity, although the frequency is low or rare.

The Causes of Rains in Dry Season in Indonesia

The unusual conditions during the wet-dry season are triggered by various natural factors. Here is an explanation of why these factors can drive changes in the dry season.

1. Atmospheric Fluctuation

Hot weather and minimal rainfall are the characteristics of a normal dry season. But, in special cases, the regional and global atmospheric dynamics can alter all of it. Atmospheric fluctuations cause the change of a dry season becomes a wet-dry season.

These atmospheric dynamics include the presence of Kelvin and Equatorial Rossby waves. Both of them carry large amounts of water vapor and increasing the formation of rain clouds out of season. The last one of the waves is the Madden-Julian Oscillation (MJO), which continues to periodically move with high humidity over Indonesia. It is causing rainfall during the dry season, although with low frequency.

Atmospheric dynamics are also influenced by cyclonic circulation. When Indonesia has a wet-dry season, there is a cyclonic circulation that forms clouds and rain during the dry season.

2. Global Weather Phenomenon

Global weather phenomena are further contributing factors, including La Niña and a negative IOD (Indian Ocean Dipole). Both significantly influence seasonal patterns and the ways to deal with them.

La Niña is a phenomenon characterized by a cooling of sea surface temperature in the central and eastern Pacific Ocean, lower than the normal temperature. This leads to increased rainfall. If this condition occurs during the dry season, the seasonal pattern shifts to a wet-dry season.

A negative IOD is a weather anomaly in the Indian Ocean, where sea surface temperatures in the central and eastern parts (around Indonesia) are cooler. When it occurs, Indonesia is an increase in rainfall.

3. Global Warming

Global warming causes the rise of sea surface temperature in tropical regions, which increases evaporation and atmospheric humidity. As a result, the strong humidity is more triggers the formation of rain clouds.

Tips to Survive in Wet-Dry Season

The wet-dry season is certainly different from a normal dry season. There are many risks of natural disasters caused by the continued rains in dry season in Indonesia. Therefore, strategies are needed to anticipate this unusual season. Here are many tips to survive in any potential risks.

1. Monitoring Weather Information

The wet dry season certainly presents a distinct phenomenon, such as rain continues to fall, although at a lower frequency. To stay updated, regularly monitor weather conditions. Authorities need to monitor weather information using the latest equipment and technology. Along with this monitoring, analysis is also needed to interpret each condition based on natural changes.

2. Repair Infrastructure

Infrastructure repair is necessary to anticipate various risks resulting from the wet-dry season. The rainy season alternates with the dry season. If it still rains during the dry season, it is needed to repair the drainage system to ensure the smooth flow of water. Moreover, it also needs to check the culverts and water channels to prevent blockages.

3. Maintain Health and Immunity

High humidity and low temperatures are the specific conditions of the wet-dry season. This condition potentially spreads coughs, flu, or fever as health problems. To avoid all health risks, recommended to maintain good hygiene and the immune system. Regularly, do a nutritious and regular diet, do regular exercise, and clean the environment.

Given the many natural factors that trigger a wet-dry season, it's crucial to take preventive measures. Rains in dry season in Indonesia can be observed by weather monitoring systems, allowing for accurate weather conditions.

Landslides and floods are the natural disasters that potentially occur in the wet-dry season. Certainly, it is needed actions to mitigate these risks. The base of the mitigation program is implementing a disaster warning system. The government can equip it with an emergency messaging system.

This specific machine is based on SMS (Short Message Service) that is available at smsbroadcaster.com. This technology facilitates delivering an emergency message in real time to mobile phones.  So, the important message that contains crucial information is received by affected people. This is an effective way to anticipate the various risks from natural disasters.
