Weather and Climate: how it affects us

Weather is about daily (diurnal) changes in weather elements. Weather refers to the atmospheric conditions at a specific place (location) over a short period of time. Climate is about long term trends and generalisations of the weather over a long period of time (30-35 years). Climate refers to atmospheric conditions of a specific place (location).


A look at how weather affects populations

Weather is the state of the air at a particular place and time - warm or cold, wet or dry, cloudy or windy or the likes. Climate is the normal pattern of weather experienced in a particular area over a long period.
The weather and climate of a place has always affected populations. Throughout history, humanity has always been in awe of the weather, and weather still plays a big part in our lives today. It affects many of the things that we do, from the clothes we wear and the food we eat, to where we live and how we travel.

Since the dawn of history human settlements, migrations and growth has depended on weather conditions. All the great civilizations and empires have flourished near rivers and oceans, where the weather is moderate and suitable for the cultivation of crops and domestication of animals.
Just to cite some instances from history, it is the pleasant climate of England that attracted the various invaders of the past like Normans, Danes and others to settle down, and gradually over the years assimilate to form what is now the English population. The harsh climate of the Arabian deserts have prevented the interiors of the land from being invaded by an external force in the annals of history, and moreover was an added incentive for the Arabs to burst out from that hot and barren land to establish one of the largest empires during the medieval period. The Arabs landed in Spain initially on an expedition, and attracted by the weather, stayed and ruled there for 800 years! Many once thriving cities are now abandoned ghost towns primarily because the weather changed and people could no longer continue with their lives there. A big tsunami in the Indian Ocean in 1341 CE wrecked havoc of most of the well-established ports and led to the formation of new natural harbors in places like Cochin and Karachi, which soon developed into big cities.

Weather has an impact on the physical and mental make up of the populace as well. The culture, the way of life, the dietary habits, the clothing trends, the behavior of people coming from places where the weather in harsh differs significantly from that of people who live under docile climates. It is possible to stereotype the populace of cities and even nations based on weather related factors.

Weather also has a profound effect on human health and well-being. The hypothalamus in the human brain controls.

Weather Affects All Our Lives In Some Way

A very common proverb that is somewhat true is, no one does anything about the weather though everyone discusses about it. In fact it is one of the most common topic that people speculate and talk about. Millions of people look over the internet to know about the local and global weather and also weather hazards. All are curious about whether umbrella is required today or whether this weekend's big game is going to be spoiled by rain or not.

If you stay on the Earth, weather is bound to affect you in diverse ways. The kind of house you stay in, the type of clothes you were, even the type of leisure activities and games you enjoy - all are determined by the weather.

Weather influences the nature of the soil on which we live. Even plants and animals adapt to various living conditions due to weather variations. Depending on their surrounding weather, plants adapt to survive in extreme dry or wet conditions. The shapes of their branches also depend on the prevailing weather. Similarly, the animals also get acclimatized to endure the extremities of their natural habitat.

Even though we cannot 'do' much regarding the weather conditions, our meticulous study about the weather helps sharpen our ability to predict the approaching weather conditions. The ability to accurately foresee the oncoming adverse weather conditions help to reduce the loss to the farmers as they can modify their farming practices according to the predicted weather.

Weather conditions vary depending on the form of the atmosphere of the earth. A feature unique to the atmosphere that surrounds our world is that it contains water vapor, and a temperature that maintains this water in three different forms - solid, liquid and gas.

Technically, the day to day changes in the atmosphere conditions is referred to as the weather. Different aspects of weather like the windspeed, humidity, temperature, type and amount of precipitation etc. are measured to give us an idea of what kind of conditions we face on earth.

The sun causes these atmospheric variations and determines the condition of the atmosphere based on the location on the globe. The temperature rises up and falls down faster in land areas than oceans. The Polar Regions receive less intense radiation from the sun than the equatorial regions.

The atmosphere is a massive complex phenomenon that wants to maintain an equilibrium of its own, in the same way like every other complicated systems. The cooler regions around the poles of the earth suck in the warm air from the equatorial regions. The rotation of the earth and the friction with the land also determines the movement of air. This whole system is contained within a small area by the gravity of the earth.

Complex patterns of low and high air pressure are caused because of the combination of a variety of factors like the geography of Alicante and Benidorm in Spain, the uneven heating, balancing force of the earth to even out the irregularities, and the gravitational and rotational forces. Different weather conditions are produced as result of interaction between these low and high air pressures with the ground.
Being very passionate about Costa Calida and Alicante, Ray Walberg is writing countless long articles on this specific topic. Writing for publications on Alicante and pictures of benidorm spain the writer expressed his capability on the subject.
