He is often recognized as a bishop and is considered one of the early Christian missionaries to the region. His feast day is celebrated on different dates in various local calendars. The details about Saint Paternian are not extensively documented, leading to variations in his story and significance depending on local traditions.

Seven Sleepers' Day, also known as the Feast of the Seven Sleepers, is a Christian holiday celebrated in various traditions, primarily within the Western and Eastern Orthodox Churches. It commemorates the legend of the Seven Sleepers of Ephesus, a group of Christian youths who, according to tradition, fell asleep in a cave to escape persecution during the Roman Empire and awoke centuries later during the reign of Emperor Theodosius II.

A "sunshower" is a meteorological phenomenon that occurs when rain falls while the sun is shining. This unlikely combination often creates a striking contrast between the rain and sunlight, leading to beautiful visual effects such as rainbows. Sunshowers can happen in various regions and are typically associated with quick, passing showers that do not obscure the sun. The term is often used in literature and colloquial speech, and in some cultures, it is associated with specific folklore or beliefs.

Pyrrharctia isabella, commonly known as the Virginia tiger moth, is a species of moth in the family Erebidae. It is characterized by its distinctive yellow and black coloring, with furry bodies and wings. The adult moths are typically found in a variety of habitats, including fields, meadows, and forests throughout North America.

"Rain follows the plow" is a historical concept that pertains to agricultural practices and climate perception, particularly in the context of the American West during the 19th century. The phrase suggests that the act of plowing the land and cultivating it would bring about increased rainfall, leading to more fertile and productive farming conditions.

Kim Atienza, also known as "Kuya Kim," is a well-known television presenter, actor, and animal enthusiast in the Philippines. He gained prominence as a weatherman and a host of various television shows, most notably for his work with ABS-CBN. Atienza is recognized for his fun and engaging presentation style and his segments that often involve discussing a variety of topics, including weather, science, and animals, usually featuring unique trivia and factual information.

The Knudsen paradox refers to a phenomenon in the field of gas dynamics, particularly in the context of kinetic theory of gases. It arises when discussing the behavior of gas molecules in a low-density environment, where the mean free path (the average distance traveled between collisions) is comparable to or larger than the dimensions of the system.

The Spooklight, also known as the "Morrisite Light" or "Hornet Spook Light," is a mysterious phenomenon reported in various locations in the United States, particularly in areas like Missouri, Oklahoma, and Arkansas. It typically appears as a glowing light, often described as a small orb or ball of light that moves through the air, and it has sparked numerous legends, urban myths, and investigations over the years.

A "weather house" is a decorative item often found in homes, particularly in Europe. It typically consists of a small wooden or ceramic structure that features two figures—usually a man and a woman—who emerge from the house based on the weather conditions. The mechanism typically works as follows: - **Fair Weather**: When the weather is clear or sunny, the figure of the man may emerge from the house, indicating good weather.

A "White Christmas" refers to a Christmas Day when there is snow on the ground or when snow falls on that day. The definition can vary slightly based on regional traditions, but generally, it indicates that either snow cover exists or fresh snowfall occurs on December 25th. Many people associate a White Christmas with a festive and nostalgic atmosphere, often inspired by cultural depictions in films, music, and literature.

Military weather units and formations refer to the specialized organizations and groups within armed forces that are responsible for gathering, analyzing, and disseminating meteorological and climatological information to support military operations. These units play a critical role in planning, executing, and adapting military missions by providing essential weather data that can influence decision-making.

3D nowcasting is a real-time forecasting technique used primarily in meteorology to predict weather conditions over a short time frame — typically from minutes to a few hours ahead. Unlike traditional forecasting that might use 2D models, 3D nowcasting takes into account the three-dimensional structure of the atmosphere, allowing meteorologists to represent and analyze data in three spatial dimensions (longitude, latitude, and altitude).

Aerography is a branch of meteorology that deals with the measurement and analysis of atmospheric conditions, particularly focusing on the distribution of various meteorological elements such as temperature, humidity, pressure, and wind at different altitudes. It involves the use of aeronautical observations and techniques to examine how these atmospheric variables change with height, which is crucial for understanding weather patterns, forecasting, and aviation safety.

Aeromancy is a form of divination that involves interpreting atmospheric phenomena, particularly the winds and clouds, to gain insight or predict future events. The practice relies on observing changes in the weather, such as the direction of the wind, the formation and movement of clouds, and other meteorological signs. Historically, aeromancy has its roots in various cultures and traditions, where practitioners believed that the patterns and changes in the air could provide messages from the divine or indicate the outcomes of specific events.

Marine weather forecasting is the process of predicting weather conditions over the ocean and coastal areas. It is essential for a variety of maritime activities, including shipping, fishing, recreational boating, and naval operations. Marine weather forecasts take into account a range of factors, including wind speed and direction, wave heights, tides, atmospheric pressure, temperature, visibility, and precipitation.

The National Hurricane Center (NHC) is a branch of the National Oceanic and Atmospheric Administration (NOAA), specifically under the National Weather Service (NWS) in the United States. It is responsible for monitoring, forecasting, and providing information about tropical weather systems, including hurricanes and tropical storms.

The Ocean Prediction Center (OPC) is a branch of the National Oceanic and Atmospheric Administration (NOAA) in the United States, which focuses on providing forecasts and information related to ocean and marine weather. The OPC specializes in monitoring and forecasting marine weather conditions, including ocean currents, wave heights, and potential hazards such as storms and heavy seas that can affect both maritime operations and coastal areas.

PERSIANN, which stands for Precipitation Estimation from Remote Sensing Information using Artificial Neural Networks, is a system developed for estimating precipitation using satellite-based data. It leverages artificial neural networks to analyze and interpret remote sensing data, such as infrared satellite imagery, in order to provide estimates of rainfall and precipitation patterns. PERSIANN is particularly useful for regions where traditional ground-based precipitation measurements are scarce or unavailable.
