Global Map – Wind, Weather, Ocean

Wan’t to have a look at present condition of wind, weather and ocean

Here it is

You can see high winds, low pressure regions, hurricanes, typhoons, cyclones, arctic air circulation, ITCZ ( inter tropical convergence Zone).

Pretty useful, when planning travels or any of your solo outdoor adventures. Although don’t follow it just like that, combine it with local weather forecasts, but its fun and lot of learning by just looking at this.


Malthus is true but needs Revision

Thomas Robert Mathus theory, “Principle of Population” proposed that human population grows exponentially,while food production grows at an arithmetic rate.

Malthus theory has been questioned by many and there exist many critique for the same. Malthus theory’s final result targets towards the available food for the population, but in reality this theory needs revision, there needs to be added other factors.

Population Growth+Energy Demand+Environmental Degradation together will bring the final output i.e. decreased availability of quality and real food.

Quality & Real Food, is it really available today, genetic research has led to genetically modified crops, which are drought and bug resistant, need less water; this all sounds good, but what about the production and distribution.

Further, these days there are lot of synthetic food products in the market, so no quality food here.

Weather, Climate & Atmosphere, are they the same thing?

Atmosphere is the air that surrounds us and the difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere “behaves” over relatively long periods of time.

Meteorology is the science of weather & Climatology is science of Climate.

Meteorology is the science of weather. The three basic aspects of meteorology are observation, understanding and prediction of weather. There are many kinds of routine meteorological observations. Some of them are made with simple instruments like the thermometer for measuring temperature or the anemometer for recording wind speed. Weather data is collected using satellites and other means and these are plotted on weather charts and analyzed at forecasting centers. Weather forecasts are then made.

is how the atmosphere “behaves” over relatively long periods of time & Climatology is science of Climate.

Do climates change? Yes. Climates may undergo large permanent changes and short-term changes.

Take Rainforest as an example, look at the annual temperatures. They vary in a specific way. If we cut down all of the trees in the forest, the temperatures will heat up. Since it is unlikely the forest will be able to grow back for hundreds of years, you would see a long-term climate change.

El Nino and La Nina are known as short term climate change.
