The phenomenon of rain in the dry season as an anomaly, what is a meteorological anomaly?

TIME.CO, Jakarta – Weather is an important aspect of our lives, influencing daily activities, agriculture, business and even everyday decisions, such as what to wear when leaving the house. However, sometimes the weather can be very unusual or not as expected. This phenomenon is known as meteorological anomalies.

What is a weather anomaly?

Weather anomalies are weather inconsistencies that occur when actual weather conditions differ significantly from those expected within a given time period.

Quoted from National Weather Serviceanomalous deviations in temperature or precipitation that may occur over thirty years in a given region.

Anomalies may include temperatures that are much warmer or colder than normal, unexpected rain, prolonged drought, or other extreme weather that is inconsistent with seasonality or historical norms.

In climate change studies, temperature anomalies are more important than absolute temperatures. Second National Centers for Environmental Information, the temperature anomaly is a difference from the average temperature or the base temperature. Baseline temperatures are usually calculated by averaging temperature data over 30 years or more.

A positive anomaly indicates that the observed temperature is warmer than the base temperature, while a negative anomaly indicates that the observed temperature is colder than the base temperature.

Factors influencing meteorological anomalies

There are several factors that can cause weather anomalies, including:

1. Climate change


Global climate change may result in more frequent and extreme weather anomalies. Global warming, for example, could lead to unusually high temperatures in some regions or more severe droughts.

2. Natural factors

Quoted from the site East Java Province Communication and Information Service, weather anomalies occur because they are caused by different natural factors, such as La Nina and El Nino. These two natural factors can cause weather anomalies by disrupting normal weather patterns around the world.

3. Human influence

Human activities such as urbanization, deforestation and air pollution can influence local weather patterns. Large cities often have higher temperatures than the surrounding countryside, known as “urban heat islands”.
