What is Environment

We always think of weather wherever we may be.weather is a one of the first things we notice after we wake up.if it is cold,we wear a sweater.if it is hot and sunny, wear light cotton clothes.we may be also look at the weather forecast in a newspaper, or on the internet ,in case we have to go out for a picnic, or for a holiday break but ways weather simply? let us find out.

                      

              

Weather is the state of atmosphere at a particular time and place of certain well defined terms or these element are temperature,humidity,cloudiness,precipitation and atmospheric pressure these condition are studied in meteorology the science understanding weather and weather forecasting.

Meteorologist (scientist who study weather) record these element of the weather every day. such constant recording of weather information helps determining the climate of given region.

The weather element

Temperature

Temperature is a indicator of degree of hotness and coldness of the air. temperature on the earth average(15 degree C ) at a sea level but various according to latitude elevation seasons and time of day .it can range from the record high to 58 degree c a record low of -88 degree. temperature is generally highest in the tropics and lowest near the poles. on any given day it is usually warmest 

during mid after noon and coldest around dawn just before sunrise.

Humidity 

Humidity is measure of the  amount of the water vapour in the atmosphere.the most common measure of humidity is the the relative humidity.it equals the amount of water vapour actually present in the atmosphere.divided by the atmosphere.maximum water vapour holding capacity at the atmosphere.

Cloudiness  

Most cloud are produced due to cooling of air as it rises up.when air temperature gets reduce.the excess water vapour in the air condenses into liquid  droplets,or ice crystals to from clouds or fog. fog refer to cloud that almost touch the ground.in dense fog ,the visibility range may be around 50 m or  so.

Precipitation

Precipitation is produced when the droplet and crystal in clouds grow large enough to fall on the ground. precipitation takes the variety of forms including rain drizzle,snow,hail, ice pellets,or sleet.

Wind

The horizontal movement of air referred to as the wind it is  name after the direction from which it comes  for example  a wind coming from north is known as  the northern wind in most places near the ground the wind speed usually average from 8 km/hr to 24 km/hr however  it can be very much higher during intense storms.

atmosphere pressure

It plays a vital role in the weather system atmosphere pressure is the force  due to the weight of the air on a given surface divided by the area of  that surface falling pressure usually indicates an approaching storm rising pressure usually indicates clear sky.
