Climatic Controls

Cold currents can reduce coastal temperature. In exams connect cold current with cooling effect.

Latitude and altitude are controls while temperature and rainfall are elements. In exams keep controls and elements separate.

Temperature is a measured element of climate. In exams treat temperature as element and latitude as control.

Latitude is a control that affects climate. In exams write latitude as a climatic control.

Distance from sea affects the climate of a place. In exams treat distance from sea as a control.

Temperature is a measurable element of climate. In exams remember temperature rainfall and wind as elements.

The Himalaya acts like a climatic barrier. In exams connect the Himalaya with climatic barrier.

Monsoon is mainly associated with the pressure and wind system. Unequal heating of land and sea creates pressure differences, causing winds to reverse seasonally and producing monsoon winds. Latitude, distance from the sea, and relief also affect climate, but they are not the main control behind the seasonal wind system of monsoon. Exam tip: Link monsoon with pressure differences and seasonal reversal of winds.

Near the sea extreme temperature difference may be lower. In exams connect nearness to sea with moderate climate.

Delhi is inland so continental effect can be greater. In exams understand Delhi and Mumbai through inland coastal difference.

Mumbai is a coastal city so the sea moderates temperature. In exams connect coastal location with equable climate.

Temperature decreases as altitude increases. In exams write altitude in mountains and plains comparison.

Latitude affects the angle of Sun rays. In exams connect equator and poles with latitude.

Relief especially mountains affects winds and rainfall. In exams connect relief with rainfall distribution.

Distance from sea shows coastal and continental influence. In exams remember it as a climatic control.

Altitude indicates the height of a place above sea level and helps identify its relief. A high-altitude area is generally hilly or mountainous, whereas a broad low-altitude area is usually a plain. Latitude affects climate, but it does not directly show whether a place is hilly or plain. Exam tip: For identifying relief, look for altitude or elevation.

Latitude controls the angle of Sun rays. In exams connect direct and slanting rays with latitude.

Wind can bring moisture or dryness from its source region. In exams connect wind direction with moisture source.

Mountains and relief form physical barriers in the path of winds, so they can block winds or change their direction. For example, the Himalayas reduce the effect of cold winds coming from Central Asia into India. Latitude mainly affects temperature, while distance from the sea and ocean currents chiefly influence temperature and humidity. Exam tip: when a question mentions blocking or deflecting winds, look for relief or mountains.

Climatic controls explain why climates differ across regions. In exams connect regional variation with controls.
