How to check if specific key array element exists?

$app->get('/', function () use ($app) {
    return $app['twig']->render('index.html.twig', array(
            'weather' => $app['weather_service']->get($app['location_service']->get()),
            'location' => $app['location_service']->get())

In you twig template you can do :

{% if weather.wind.deg is defined %}
        make your things
{% endif %}
